Integration of Microsoft Identity Manager with Azure Platform-as-a-Service Services

Overview

This isn’t an out of the box solution. This is a bespoke solution that takes a number of elements and puts them together in a unique way. I’m not expecting anyone to implement this specific solution (but you’re more than welcome to) but to take inspiration from it to implement solutions relevant to your environment(s). This post supports a presentation I did to The MIM Team User Group on 14 June 2017.

This post describes a solution that;

  • Leverages an Azure WebApp (NodeJS) to present a simple website. That site can be integrated easily in the FIM/MIM Portal
  • The NodeJS website leverages an Azure Function App to get a list of users from the FIM/MIM Synchronization Server and allows the user to use typeahead functionality to find the user they want to generate a FIM/MIM object report on
  • On selection of a user, a request will be sent to another Azure Function App to generate and return the report to the user in a new browser window

This is shown graphically below.

 

Report Request UI

The NodeJS WebApp is integrated into the FIM/MIM portal. Bootstrap Typeahead is used to find the user to generate a report on. The Typeahead userlist if fulfilled by an Azure Function into the MIM Sync Metaverse. The Generate Report button fires off a call to FIM/MIM via another Azure Function into the MIM Sync and MIM Service to generate the report.

The returned report opens in a new tab in the users browser. The report contains details of the FIM/MIM connectors the user is represented on.

The values of all attributes for the users hologram from the Metaverse are displayed along with the MA the value came from and the last modified date.

Finally the metadata report from the MIM Service MA Connector Space and the MIM Service.

Prerequisites

These are numerous, but I’ve previously posted about them. You will need;

I encourage you to digest those posts to understand how to configure the prerequisites for this solution.

Additional Solution Requirements

To bring all the individual components together, there are a few additional tasks to enable this solution.

  • Enable CORS on your Azure Function App Configuration (see details further below)
  • If you want to display User Object Photos as part of the report, you will likely need to synchronize them into FIM/MIM from an authoritative source (e.g. Office365/Exchange Online)   Checkout this post  and additional details further below
  • In order to embed the NodeJS WebApp into the FIM/MIM Portal, this post provides the details. Change the target URL from PowerBI URL to your NodeJS site
  • Object Report Request WebApp (see below for sample site)

Azure Functions Cross Origin Resource Sharing (CORS)

You will need to configure CORS to allow the NodeJS WebApp to access the Azure Functions (from both local and Azure). Reflect your port number if it is different from 3000, and use the DNS name for your Azure WebApp.

Sample UI NodeJS HTML

Here is a sample HTML file for your NodeJS WebApp with the UI to provide Input for LoginID fulfilled by the NodeJS Javascript file further below.

Sample UI NodeJS JavaScript

The following NodeJS JavaScript supports the HTML UI above. It populates the LoginID typeahead box and takes the Submit Report button to fulfill the report for the desired object(s). Yes if you use the UI to select (individually) multiple different objects all will be returned in their separate output windows.

As the HTML file above indicates you will need to obtain and make available as part of your NodeJS project the typeahead.bundle.js library.

Azure PowerShell Trigger Function App for AccountNames Lookup

The following Azure Function takes the call from the load of the NodeJS WebApp to populate the typeahead userlist.

Azure PowerShell Trigger Function App for User Object Report

Similar in structure to the Username List Lookup Azure Function above, but in the ScriptBlock you embed the Report Generation Script that is detailed here. Modify for what you want to report on.

Photos in the Report

If you want to display images in your report, you will need to determine if the user has an image during the MV metadata report generation part of the script. Add the following lines (updating for the name of your Image attribute; mine is named EXOPhoto) after the Try {} Catch {} in this section $obj = @() ; foreach ($attr in $attributes.Keys)

 # Display the Objects Photo rather than Base64 string 
if ($attr.equals("EXOPhoto")){ 
   $objectphoto = "<img src=$([char]0x22)data:image/jpeg;base64,$($attributes.$attr.Values.Valuestring)$([char]0x22)>" 
   $val = "System.Byte[]" 
}

Then in the output of the HTML report at the end of the report generation insert the $objectphoto variable into the HTML stream.

# Output MIM Service Object Data 
$MIMServiceObjOut = $MIMServiceObjectMetaData | Sort-Object -Property Attribute | ConvertTo-Html -Fragment 
$htmlreport = ConvertTo-HTML -Body "$htmlcss<h1>Microsoft Identity Manager User Object Report</h1><h2>Query</h2>$sourcequery</br><b><center>$objectphoto</br>NOTE: Only attributes with values are displayed.</center></b><h2>Connector(s) Summary</h2>$connectorsummary<h2>MetaVerse Data</h2>$objectmetadata <h2>MIM Service CS Object Data</h2>$MIMServiceCSobjectmetadata <h2>MIM Service Object Data</h2>$MIMServiceObjOut" -Title "MIM Object Report" 

 

As you can see above I’ve also injected the CSS ($htmlcss) into the output stream at the beginning of the Body section.  Somewhere in your script block you will need to define your CSS values. e.g.

 # StyleSheet for nice pretty output 
$htmlcss = "<style> 
   h1, h2, th { text-align: center; } 
   table { margin: auto; font-family: Segoe UI; box-shadow: 10px 10px 5px #888; border: thin ridge grey; } 
   th { background: #0046c3; color: #fff; max-width: 400px; padding: 5px 10px; } 
   td { font-size: 11px; padding: 5px 20px; color: #000; } 
   tr { background: #b8d1f3; } 
   tr:nth-child(even) { background: #dae5f4; } 
   tr:nth-child(odd) { background: #b8d1f3; } 
</style>"

How to build and deploy an Azure NodeJS WebApp using Visual Studio Code

Introduction

This week I had the need to build a small web application with a reasonably simple front end that will later be integrated inside a Portal. The web application isn’t going to be high use and didn’t necessitate deployment of infrastructure (VM’s). I’d messed with NodeJS a while back in this post where I configured a UI for Microsoft Identity Manager and Azure based functions.

In the back of my mind I knew I didn’t want to have to go for a full Visual Studio Project Solution for this, and with the recent updates to Visual Studio Code I figured it must be possible to do it using it. There wasn’t much around on doing it, so I dived in and worked it out for myself. Here I share the end-to-end process to make it easy for you to started.

Overview

What you will need on your development workstation before you start are the following components. Download and install them on your development machine.

You will also need an Azure Subscription to where you will publish your NodeJS site.

This post details setting up Visual Studio Code to build a shell NodeJS site and deploy it to Azure using a local GIT Repository. Let’s get started.

Visual Studio Code Extensions

A really smart and handy extension for VS Code is Azure Tools for VS Code. Release a few months ago (January 2017), this extension allows you to quickly create a Web App (Resource Group, App Service, Application Service Plan etc) from within VS Code. With VSCode on your development machine from the prerequisites above click on the Extensions Icon (bottom left) in the VSCode menu and type Azure Tools. Click the green Install button.

Azure Tools for VS Code

Creating the NodeJS Site in VS Code

I had a couple of attempts at doing this before I found a quick, neat and repeatable method of getting started. In order to get the Web App deployed and accessible correctly in Azure I found it easiest to use the Sample Azure NodeJS Hello World example from here. Download that sample and extract the contents to a new folder on your workstation. I created a new path on mine named …\NodeJS\nodejssite and dropped the sample in there so it looked like below.

After creating the folder structure and putting the sample in it, whilst in the sub-directory type:

code .

That will startup Visual Studio Code in the newly created folder with the starter sample.

Install Express for NodeJS

To that base sample site we’ll install Express. From the Terminal tab in the lower pane type:

npm install -g express-generator

Express App

With Express now on our machine, lets add the Express App to our new NodeJS site. Type express in the Terminal window.

express

Accept that the directory is not empty

This will create the folder structure for Express.

Now to get all the files and modules for our site configured for our app run npm install

Now type npm start in the terminal window to start our new site.

The NodeJS site will start. Open a Web Browser and go to http://localhost:3000 and you should see the Express empty site.

Navigate to views => index.jade Update the text like I have below.

Refresh your browser window and you should see the text updated.

In the terminal windows press Cntrl + C to stop NodeJS.

Test Deploy to Azure

Now let’s do a test deploy of our shell site as an Azure WebApp.

Press Cntrl + Shift + P or from the View menu select Command Palette.

Type Azure: Login 

This will generate a code and give you a link to open in your browser and login

Paste in the code from the clipboard and select continue

Then login with your account for the Tenant where you want to deploy the WebApp too. You’ll then be authorized.

From the Command Palette type azure sub and choose Azure: List Azure Subscriptions and choose the subscription where you will create and deploy the WebApp

Now from the Command Palette type Azure Create a Web App (Simple).

Give the WebApp a name. This will become the WebApp Name, and the basis for the all the associated WebApp components. Use Create a Web App (Advanced) if you want to be more specific about the name of the App Resources etc.

If you watch the bottom VS Code Status bar you will see the Azure Tools extension create the new Resource Group, Web App and Web App Plan.

Login to the Azure Portal, select the new Web App.

Select Deployment Options and then Local Git Repository. Select OK.

Select Deployment credentials and provide a username and password. You’ll need this shortly to publish your site.

Click Overview. Copy the Git clone url.

Back in VS Code, select the GIT icon (under the magnifying glass) and from the top choose Initialize Repository.

Then in the terminal window type git remote add azure <git clone url> obtained from the step above.

Type Initial Commit as the message and click the tick icon in the Source Control menu bar.

Select and select Publish

Select azure as the remote target we setup earlier.

You’ll be prompted to authenticate. Use the account you created above in Deployment Credentials.

Back in the Azure Portal under the Web App under Deployment Options you will see the initial commit.

Click on Overview and you should see that it is running. Click on URL and the site will open in a new tab in your browser.

Updating our WebApp

Now, let’s make a change to our WebApp.

Back in VS Code, click on the files and folder icon in the top left corner, navigate to views => index.jade and update the title. Hit Cntrl + S (or select Save from the File menu). In Terminal below type npm start to start our NodeJS site locally.

Check out the update locally. In a browser navigate to the local NodeJS site on localhost:3000. You’ll see the changed page.

Select the Git icon on the left menu, give the update some text e.g. ‘updated page text’ and select the tick from the top menu.

Select the and choose Push to publish the changes to our Azure WebApp.

Go back to your browser which was on the Azure WebApp URL and reload. Our change and been push and reflected in the WebApp.

Summary

Very quickly and easily using Visual Studio Code (with NodeJS and Git Desktop installed locally) we have;

  • Created an Azure WebApp
  • Created a base NodeJS site
  • Have a local NodeJS site we can develop
  • Publish it to Azure

Now go create something awesome.

How to access Microsoft Identity Manager Hybrid Report data using PowerShell, Graph API and oAuth2

Hybrid Reporting is a great little feature of Microsoft Identity Manager. A small agent installed on the MIM Sync Server will send reporting data to Azure for MIM SSPR and MIM Group activities. See how to install and configure it here.

But what if you want to get the reporting data without going to the Azure Portal and looking at the Audit Reports ? Enter the Azure AD Reports and Events REST API that is currently in preview.  It took me a couple of cracks and getting this working, because documentation is a little vague especially when accessing it via PowerShell and oAuth2. So I’ve written it up and hope it helps for anyone else looking to go down this route.

Gotchas

Accessing the Reports via the API has a couple of caveats that I had to work through:

  • Having the correct permissions to access the report data. Pretty much everything you read tells you that you need to be a Global Admin. Once I had my oAuth tokens I messed around a little and a was able to also get the following from back from the API when purposely using an identity that didn’t have the right permissions. The key piece is “Api request is not from global admin or security admin or security reader role”. I authorized the WebApp using an account that is in the Security Reader Role, and can successfully access the report data.

How to Access the Reporting API using PowerShell

What you need to do is;

  • Register a WebApp
  • Get an oAuth2 Authentication Code using an account that is either Global Admin or in the Security Admin or Security Reader Azure Roles
  • Use your Bearer and Refresh tokens to query for the reports you’re interested in

Register your WebApp

In the Azure Portal create a new Web app/API app and assign it https://localhost as the Reply URL. Record the Application ID for use in the PowerShell script.

Assign the Read Directory data permission as shown below

Obtain a key from the Keys option on your new Web App.  Record it for use in the PowerShell script.

Generate an Authentication Code, get a Bearer and Refresh Token

Update the following script, changing Lines 5 & 6 for the ApplicationID/ClientId and Client Secret for the WebApp you created above.

Run the script and you will be prompted to authenticate. Use an account in the tenant where you created the Web App that is a Global Admin or in the Security Admin or Security Reader Azure Roles. You will need to change the location where you want the refresh.token stored (line 18).

If you’ve done everything correctly you have authenticated, got an AuthCode which was then used to get your Authorization Tokens. The value of the $Authorization variable should look similar to this;

Now you can use the Refresh token to generate new Authorization Tokens when they time out, simply by calling the Get-NewTokens function included in the script above.

Querying the Reporting API

Now that you have the necessary prerequisites sorted you can query the Reporting API.

Here are a couple of simple queries to return some data to get you started. Update the script for the tenant name of your AzureAD. With the $Authorization values from the script above you can get data for the MIM Hybrid Reports.

Synchronizing Exchange Online/Office 365 User Profile Photos with FIM/MIM

Introduction

This is Part Two in the two-part blog post on managing users profile photos with Microsoft FIM/MIM. Part one here detailed managing users Azure AD/Active Directory profile photo. This post delves deeper into photos, specifically around Office 365 and the reason why you may want to manage these via FIM/MIM.

Background

User profile photos should be simple to manage. But in a rapidly moving hybrid cloud world it can be a lot more complex than it needs to be. The best summary I’ve found of this evolving moving target is from Paul Ryan here.

Using Paul’s sound advice we too are advising our customers to let users manage their profile photo (within corporate guidelines) via Exchange Online. However as described in this article photos managed in OnPremise Active Directory are synchronized to Azure AD and on to other Office365 services only once. And of course we want them to be consistent across AD DS, Azure AD, Exchange Online and all other Office365 Services.

This post details synchronizing user profile photos from Exchange Online to MIM for further synchronization to other systems. The approach uses a combination of Azure GraphAPI and Exchange Remote PowerShell to manage Exchange Online User Profile Photos.

The following graphic depicts the what the end goal is;

Current State

  • Users historically had a photo in Active Directory. DirSync/ADSync/AzureADConnect then synchronized that to Azure AD (and once only into Office 365).
  • Users update their photo in Office365 (via Exchange Online and Outlook Web Access)
    • the photo is synchronized across Office365 Services

Desired State

  • An extension of the Current State is the requirement to be able to take the image uploaded by users in Exchange Online, and synchronize it back to the OnPremise AD, and any other relevant services that leverage a profile photo
  • Have AzureADConnect keep AzureAD consistent with the new photo obtained from Office365 that is synchronized to the OnPrem Active Directory
  • Sync the current photo to the MIM Portal

Synchronizing Office365 Profile Photos

Whilst Part-one dealt with the AzureAD side of profile photos as an extension to an existing AzureAD PowerShell Management Agent for FIM/MIM, I’ve separated out the Office365 side to streamline it and make it as efficient as possible. More on that later. As such I’ve created a new PowerShell Management Agent specifically for Office365 User Profile Photos.

I’m storing the Exchange Online photo in the MIM Metaverse as a binary object just as I did for the AzureAD photo (but in a different attribute ). I’m also storing a checksum of the photos (as I did for the AzureAD Photo, but also in a different attribute) to make it easier for comparing what is in Azure AD and Exchange Online, to then be used to determine if changes have been made (eg. user updated their profile photo).

Photo Checksum

For generating the hash of the profile photos I’m using Get-Hash from the Powershell Community Extensions.  Whilst PowerShell has Get-FileHash I don’t want to write the profile photos out to disk and read them back in just to get the checksum. That slows the process up by 25%. You can get the checksum using a number of different methods and algorithms. Just be consistent and use the same method across both profile photos and you’ll be comparing apples with apples and the comparison logic will work.

Some notes on Photos and Exchange Online (and MFA)

This is where things went off on a number of tangents. Initially I tried accessing the photos using Exchange Online Remote PowerShell.

CAVEAT 1: If your Office365 Tenant is enabled for Multi-Factor Authentication (which it should be) you will need to get the Exchange Online Remote PowerShell Module as detailed here. Chances are you won’t have full Office365 Admin access though, so as long as the account you will be using is in the Recipient Management Role you should be able to go to the Exchange Control Panel using a URL like https://outlook.office365.com/ecp/?realm=&lt;tenantname>&wa=wsignin1.0 where tenantname is something like customer.com.au From the Hybrid menu on in the right handside pane you will then be able to download the Microsoft.Online.CSE.PSModule.Client.application I had to use Internet Explorer to download the file and get it installed successfully. Once installed I used a few lines from this script here to load the Function and start my RPS session from within PowerShell ISE during solution development.

CAVEAT 2: The EXO RPS MFA PS Function doesn’t allow you to pass it your account password. You can pass it the identity you want to use, but not the password. That makes scheduled process automation with it impossible.

CAVEAT 3: The RPS session exposes the Get-UserPhoto cmdlet which is great. But the RPS session leverages the GraphAPI. The RPS PS Module doesn’t refresh it’s tokens, so if the import takes longer than 60 minutes then using this method you’re a bit stuffed.

CAVEAT 4: Using the Get-UserPhoto cmdlet detailed above, the syncing of photos is slow. As in I was only getting ~4 profile photos per minute slow. This also goes back to the token refresh issue as for pretty much any environment of the size I deal with, this is too slow and will timeout.

CAVEAT 5: You can whitelist the IP Address (or subnet) of your host so MFA is not required using Contextual IP Addressing Whitelisting. At that point there isn’t really a need to use the MFA Enabled PREVIEW EXO RPS function anyway. That said I still needed to whitelist my MIM Sync Server(s) from MFA to allow integration into the Graph API. I configured just the single host. The whitelist takes CIDR format so that looks like /32 (eg. 11.2.33.4/32)

Performance Considerations

As I mentioned above,

  • using the Get-UserPhoto cmdlet was slow. ~4 per minute slow
  • using the GraphAPI into Exchange Online and looking at each user and determining if they had a photo then downloading it, was also slow. Slow because at this customer only ~50% of their users have a photo on their mailbox. As such I was only able to retrieve ~145 photos in 25 minutes. *Note: all timings listed above were during development and actually outputting the images to disk to verify functionality. 

Implemented Solution

After all my trial and error on this, here is my final approach and working solution;

  1. Use the Exchange Online Remote PowerShell (non-MFA version) to query and return a collection of all mailboxes with an image *Note, add an exception for your MIM Sync host to the white-listed hosts for MFA (if your Office365 Tenant is enabled for MFA) so the process can be automated
  2. Use the Graph API to obtain those photos
    • with this I was able to retrieve ~1100 profile photos in ~17* minutes (after ~2 minutes to query and get the list of mailboxes with a profile photo)

Pre-requisites

There’s a lot of info above, so let me summarize the pre-requisties;

  • The Granfeldt PowerShell MA
  • Whitelist your FIM/MIM Sync Server from MFA (if your Office 365 environment is enabled for MFA)
  • Add the account you will run the MA as, that will in turn connect to EXO via RPS to the Recipient Management Role
  • Create a WebApp for the PS MA to use to access users Profile Photos via the Graph API (fastest method)
  • Powershell Community Extensions to generate the image checksum

Creating the WebApp to access Office365 User Profile Photos

Go to your Azure Portal and select the Azure Active Directory Blade from the Resource Menu bar on the left. Then select App Registrations and from the Manage Section of the Azure Active Directory menu, and finally from the top of the main pane select “New Application Registration“.

Give it a name and select Web app/API as the type of app. Make the sign-in URL https://localhost and then select Create.

Record the ApplicationID that you see in the Registered App Essentials window. You’ll need this soon.

Now select All Settings => Required Permissions. Select Read all users basic profiles in addition to Sign in and read user profile. Select Save.

Under Required Permissions select Add and then select 1 Select an API, and select Office 365 Exchange Online then click Select.

Choose 2 Select Permissions and then select Read user profiles and Read all users’ basic profiles. Click Select.

Select Grant Permissions

From Settings select Keys, give your key a Description, choose a key lifetime and select Save. RECORD the key value. You’ll need this along with the WebApp ApplicationID/ClientID for the Import.ps1 script.

Using the information from your newly registered WebApp, we need to perform the first authentication (and authorization of the WebApp) to the Graph API. Taking your ApplicationID, Key (Client Secret) and the account you will use on on the Management Agent (and that you have assigned the Recipient Management Role in Exchange Online) and run the script detailed in this post here. It will authenticate you to your new WebApp via the GraphAPI after asking you to provide the account you will use on the MA and Authorizing the permissions you selected when registering the app. It will also create a refresh.token file which we will give to the MA to automate our connection. The Authorization dialog looks like this.

Creating the Management Agent

Now we can create our Management Agent using the Granfeldt PowerShell Management Agent. If you haven’t created one before checkout a post like this one, that further down the post shows the creation of a Granfeldt PSMA. Don’t forget to provide blank export.ps1 and password.ps1 files on the directory where you place the PSMA scripts.

PowerShell Management Agent Schema.ps1

PowerShell Management Agent Import.ps1

As detailed above the PSMA will leverage the WebApp to read users Exchange Profile Photos via the Graph API. The Import script also leverages Remote Powershell into Exchange Online (for reasons also detailed above). The account you run the Management Agent as will need to be added to the Recipient Management Role Group in order to use Remote PowerShell into Exchange Online and get the information required.

Take the Import.ps1 script below and update;

  • Update lines 11, 24 and 42 for the path to where you have put your PSMA. Mine is under the Extensions directory in a directory named EXOPhotos.
  • copy the refresh.token generated when authenticating and authorizing the WebApp earlier into the directory you specified in line 42 above.
  • Create a Debug directory under the directory you specified in lines 11,24 and 42 above so you can see what the MA is doing as you implement and debug it the first few times.
  • I’ve written the Import to use Paged Imports, so make sure you tick the Paged Imports checkbox on the configuration of the MA
  •  Update Lines 79 and 80 with your ApplicationID and Client Secret that you recorded when creating your WebApp

Running the Exchange User Profile Photos MA

Now that you have created the MA, you should have select the EXOUser ObjectClass and the attributes defined in the schema. You should also create the EXOPhoto (as Binary) and EXOPhotoChecksum (as String) attributes in the Metaverse on the person ObjectType (assuming you are using the built-in person ObjectType).

Configure your flow rules to flow the EXOPhoto and EXOPhotoChecksum on the MA to their respective attributes in the MV.

Create a Stage Only run profile and run it. If you have done everything correctly you will see photos come into the Connector Space.

Looking at the Connector Space, I can see EXOPhoto and EXOPhotoChecksum have been imported.

After performing a Synchronization to get the data from the Connector Space into the Metaverse it is time to test the image that lands in the Metaverse. That is quick and easy via PowerShell and the Lithnet MIIS Automation PowerShell Module.

$me = Get-MVObject -ObjectType person -Attribute accountName -Value "drobinson"
$me.Attributes.EXOPhoto.Values.ValueBinary
[System.Io.File]::WriteAllBytes("c:\temp\myOutlookphoto.jpg" ,$me.Attributes.EXOPhoto.Values.ValueBinary )

The file is output to the directory with the filename specified.

Opening the file reveals correctly my Profile Photo.

Summary

In Part one we got the AzureAD/Active Directory photo. In this post we got the Office365 photo.

Now that we have the images from Office365 we need to synchronize any update to photos to Active Directory (and in-turn via AADConnect to Azure AD). Keep in mind the image size limits for Active Directory and that we retrieved the largest photo available from Office365 when synchronizing the photo on. There are a number of PowerShell modules for photo manipulation that will allow you to resize accordingly.

How to Synchronize users Active Directory/Azure Active Directory Photo using Microsoft Identity Manager

Introduction

Whilst Microsoft FIM/MIM can be used to do pretty much anything your requirements dictate, dealing with object types other than text and references can be a little tricky when manipulating them the first time. User Profile Photos fall into that category as they are stored in the directory as binary objects. Throw in Azure AD and obtaining and synchronizing photos can seem like adding a double back-flip to the scenario.

This post is Part 1 of a two-part post. Part two is here. This is essentially the introduction to the how-to piece before extending the solution past a users Active Directory Profile Photo to their Office 365 Profile Photo. Underneath the synchronization and method for dealing with the binary image data is the same, but the API’s and methods used are different when you are looking to implement the solution for any scale.

As for why you would want to do this, refer to Part two here. It details why you may want to do this.

Overview

As always I’m using my favourite PowerShell Management Agent (the Granfeldt PSMA). I’ve updated an existing Management Agent I had for Azure AD that is described here. I highly recommend you use that as the basis for the extra photo functionality that I describe in this post. Keep in mind the AzureADPreview, now AzureAD Powershell Module has change the ADAL Helper Libraries. I detail the changes here so you can get AuthN to work with the new libraries.

Therefore the changes to my previous Azure AD PowerShell MA are to add two additional attributes to the Schema script, and include the logic to import users profile photo (if they have one) in the Import script.

Schema.ps1

Take the schema.ps1 from my Azure AD PSMA here and add the following two lines to the bottom (before the $obj in the last line where I’ve left an empty line (29)).

$obj | Add-Member -Type NoteProperty -Name "AADPhoto|Binary" -Value 0x20 
$obj | Add-Member -Type NoteProperty -Name "AADPhotoChecksum|String" -Value "23973abc382373"

The AADPhoto attribute of type Binary is where we will store the photo. The AADPhotoChecksum attribute of type String is where we will store a checksum of the photo for use in logic if we need to determine if images have changed easily during imports.

Import.ps1

Take the import.ps1 from my Azure AD PSMA here and make the following additions;

  • On your MIM Sync Server download/install the Pscx PowerShell Module.
    • The Pscx Powershell Module is required for Get-Hash (to calculate Image checksum) based on variables vs a file on the local disk
    • You can get the module from the Gallery using Install-Module Pscx -Force
    • Add these two lines up the top of the import.ps1 script. Around line 26 is a good spot
# Powershell Module required for Get-Hash (to calculate Image checksum)
Import-Module Pscx
  • Add the following lines into the Import.ps1 in the section where we are creating the object to pass to the MA. After the $obj.Add(“AADCity”,$user.city) line is a good spot. 
  • What the script below does is create a WebClient rather than use Invoke-RestMethod or Invoke-WebRequest to get the users Azure AD Profile image only if the ‘thumbnailPhoto@odata.mediaContentType’ attribute exists which indicates the user has a profile photo. I’m using the WebClient over the PowerShell Invoke-RestMethod or Invoke-WebRequest functions so that the returned object is in binary format (rather than being returned as a string), which saves having to convert it to binary or output to a file and read it back in. The WebClient is also faster for transferring images/data.
  • Once the image has been returned (line 8 below) the image is added to the object as the attribute AADPhoto to be passed to the MA (line 11)
  • Line 14 gets the checksum for the image and adds that to the AADPhotoChecksum attribute in line 16.

Other changes

Now that you’ve updated the Schema and Import scripts, you will need to;

  • Refresh your schema on your Azure AD PSMA to get the new attributes (AADPhoto and AADPhotoChecksum) added
  • Select the two new attributes in the Attributes section of your Azure AD PSMA
  • Create in your MetaVerse via the MetaVerse Designer two new attributes on the person (or whatever ObjectType you are using for users), for AADPhoto and AADPhotoChecksum. Make sure that AADPhoto is of type Binary and AADPhotoChecksum is of type string.

  • Configure your Attribute Flow on your Azure AD PSMA to import the AADPhoto and AADPhotoChecksum attributes into the Metaverse. Once done and you’ve performed an Import and Sync you will have Azure AD Photos in your MV.

  • How do you know they are correct ? Let’s extract one from the MV, write it to a file and have a look at it. This small script using the Lithnet MIIS Automation PowerShell Module makes it easy. First I get my user object from the MV. I then have a look at the text string version of the image (to make sure it is there), then output the binary version to a file in the C:\Temp directory.
$me = Get-MVObject -ObjectType person -Attribute accountName -Value "drobinson"
[string]$myphoto = $me.Attributes.AADPhoto.Values.ValueString
[System.Io.File]::WriteAllBytes("c:\temp\UserPhoto.jpg" ,$me.Attributes.AADPhoto.Values.ValueBinary )
  • Sure enough. The image is valid.

Conclusion

Photos are still just bits of data. Once you know how to get them and manipulate them you can do what ever you need to with them. See Part two that takes this concept and extends it to Office 365.

A quick start guide to leveraging the Azure Graph API with PowerShell and oAuth 2.0

Introduction

In September 2016 I wrote this post detailing integrating with the Azure Graph API via PowerShell and oAuth 2.0.

Since that point in time I’ve found myself doing considerably more via PowerShell and the Graph API using oAuth. I regularly find myself leveraging previous scripts to generate a new script for the initial connection. To the point that I decided to make this simpler and provide a nice clean starting point for new scripts.

This blog post details a simple script to generate a couple of PowerShell Functions that can be the basis for integration with Graph API using PowerShell via a WebApp using oAuth2.

Overview

This script will request the necessary information required to call into the Graph API and establish a session. Specifically;

Armed with this information the shell of a PowerShell script will be created that will;

  • Authenticate a user to Graph API via Powershell and oAuth 2.0
  • Request Authorization for the WebApp to access the Scope provided (if Admin approval scope is requested and the AuthN is performed by a non-admin an authorization failure message will appear detailing an Administrator must authorize).
  • Obtain and Authorization Code which will contain the Bearer Token and Refresh Token.
    • The Bearer token can be used to make Graph API calls for up to 1 hour.
    • The Refresh token will allow you to request a new token and allow your script to be used again to interact via Graph API without going through the Authentication process again.

The following graphic shows this flow.

Create/Register your Application

Go to the Application Registration Portal https://apps.dev.microsoft.com/ and sign in. This is the new portal for registering your apps. It will show any previous apps you registered within AzureAD and any of the new “Converged Apps” you’ve created via the new Application Registration Portal.

Select Add an app from the Converged applications list.

Give your app a name and select Create

Record the Application ID (previously known as the Client ID) and select Generate New Password.

You will be provided your Client Secret. Record this now as it is the only time you will see it. Select Ok.

By default you will get User.Read permissions on the API. That is enough for this sample. Depending on what you will do with the API you will probably need to come and change the permissions or do it dynamically via the values you supply the $resource setting in your API calls.

Select Platforms, select Web and add a reply URL of https://localhost

Scroll to the bottom of the Registration windows and select Save.

Generate your PowerShell Graph API oAuth Script

Copy the following script and put it into an Administrator PowerShell/PowerShell ISE session and run it.

It will ask you to choose a folder to output the resultant PowerShell Script to. You can create a new folder through this dialog window if require.

The script will prompt you for the Client/Application ID, Client Secret and the Reply URL you obtained when registering the Web App in the steps above.

The script will be written out to the folder you chose in the first step and it will be executed. It will prompt you to authenticate. Provide the credentials you used when you created the App in the Application Registration Portal.

You will be prompted to Authorize the WebApp. Select Accept

If you’ve executed the previous steps correctly you’ll receive an AuthCode in your PowerShell output window

You’ll then see the output for a sample query for your user account and below that the successful call for a refresh of the tokens.

Summary

In the folder you chose you will find a PowerShell script with the name Connect-to-Microsoft-Graph.ps1You will also find a file named refresh.token. You can use the script to authenticate with your new app, but more simply use the Get-NewTokens function to refresh your tokens and then write your own API queries to your app using the tokens. Unless you change the scope you don’t need to run Get-AzureAuthN again. Just use Get-NewTokens before your API calls.

e.g

Get-NewTokens  
$myManager = Invoke-RestMethod -Method Get -Headers @{Authorization = "Bearer $accesstoken"
 'Content-Type' = 'application/json'} `
 -Uri "https://graph.microsoft.com/v1.0/me/manager"

 $myManager

Change the scope of your app to get more information. If you add a scope that requires Admin consent (and you’re not an admin), when prompted to authenticate you will need to get an Admin to authenticate and authorize the scope. Because you’ve changed the scope you will need to run the Get-AzureAuthN function again after updating $scope (as per below) and the dependent $scopeEncoded.

As the screen shot below shows I added the Mail.Read permission. I changed the $scope in the script so that it reflected the changes e.g

#Scope
$scope = "User.Read Mail.Read"
$scopeEncoded = [System.Web.HttpUtility]::UrlEncode($scope)

When running the script again (because of the change of scope) you will be prompted to confirm the change of access.

You can then query your inbox, e.g.

 $myMail = Invoke-RestMethod -Method Get -Headers @{Authorization = "Bearer $accesstoken"
 'Content-Type' = 'application/json'} `
 -Uri "https://graph.microsoft.com/v1.0/me/messages"
 $mymail

And there is mail messages from your inbox.

I hope that makes getting started with the oAuth2 Graph API via PowerShell a lot simpler than it was for me initially, with the differing endpoints, evolving API and the associated documentation somewhere in-between.

Using the Lithnet PowerShell Modules to generate full object metadata FIM/MIM HTML Reports

How many times have you wanted a consolidated report out of FIM/MIM for an object? What connectors does it have, what are the values of the attributes, which Management Agent contributed the value(s) and when? Individually of course you can get that info using the Metaverse Search and looking at the object in MIM Portal. But what if you wanted it all with a single query? This blog post provides an approach to doing just that. The graphic above shows a screenshot of a sample output. Click this Sample Report for full resolution version of the screenshot above. Note: The updated version of the script below outputs DisplayName for the ExpectedRulesList attribute so it actually provides valuable information. 

Overview

The approach is quite simple. It is;

  • Query the FIM/MIM Metaverse for an object
  • Take the response from the Metaverse to build the Connectors and Metaverse Hologram reports
  • Use the connector information to query the MIM Service MA (this example assumes it is on the same server. If not add the following line into the script with the appropriate values) and get the objects MIM Service Connector Space info
    Set-ResourceManagementClient -BaseAddress http://fimsvc:5727;
  • Take information retrieved above to then query the MIM Service and return the information for the object.
  • Format all the output for HTML, apply a simple style sheet, output to file and display in the default browser

NOTE: If you combine this with the Get-MVObject query building script detailed here it can be a relatively simple solution. That script even uses the same variables $queries and $query as outputs from the search and input into the HTML Report.

NOTE: You could possibly run it remotely from the MIM Sync Server too, if you leverage Remote Powershell to your FIM/MIM Sync server as detailed here.

The Script

Here it is. Lines 23 and 24 contain a hard-coded query. Update for your search criteria, or as detailed above combine this with the Get-MVObject query building script detailed here .  The Output directory specified in Line 7 is where the stylesheet and the resultant HTML file will be placed. Update for your needs.

For the Expected Rules List (unlike the screenshot as I’ve modified the script afterwards), the script gets the DisplayName for them and puts that in the report. DisplayName is more valuable than an ERE ObjectID.

Scripting queries for Lithnet Get-MVObject searches into the Microsoft Identity Manager Metaverse

It probably seems obvious by now, but I seem to live in PowerShell and Microsoft Identity Manager. I’m forever looking into the Microsoft Identity Manager Metaverse for objects.

However, sometimes I get tripped up by the differences in Object Classes between the FIM/MIM Service and the Metaverse, the names of the Object Classes (obviously not Person, Group and Contact) and in situations where they are case-sensitive.  If you’re using the Sync Service Manager Metaverse Search function though you get a pick list. But getting the data out to do something else with isn’t an option.

Solution

I’ve looked to quickly provide a similar function to the pick lists in the Metaverse Search GUI via Powershell which then gets executed by the Get-MVObject PowerShell Module.

UPDATE: 17 May 2017 The Lithnet MIIS Automation PowerShell Module has been updated for Get-MVObject to support the ObjectType Scope. I’ve updated the script to include the scope parameter based on the ObjectClass selected at the beginning of the script. 

I’ve defaulted the ObjectClass to Person so you can just press enter. But if you have custom ObjectClasses in your Metaverse you may need to change the index number in Line 48 from 5 to whichever index Person appears in your environment. Same goes for the default attribute of AccountName in the Attribute list. It appears at index 5 (Line 77) in my attribute list.

Process

Basically just run the PowerShell script and choose your options. The script needs interaction with the FIM/MIM Sync server, so you run it from the FIM/MIM Sync server. If you want to run it remotely (of course you do), then Remote PowerShell is your friend. Checkout how to do that to the FIM/MIM Server in this post here.

The Script itself will query the FIM/MIM MV Schema and return a list of Object Classes. As detailed above, in Line 48 of the script I have ‘index 5’ as the default which in my environment is Person and as such you can just hit enter if that is the Object Class you want to choose attributes from in the next step. Otherwise type the name of the ObjectClass you want. You don’t have to worry about case sensitivity as the script handles that. You can only choose a single ObjectClass obviously, but the menu ui I’ve used allows for multiple selections. Just press enter when prompted for another option for ObjectClass.

You’ll then be presented with a list of attributes from the chosen Object Class above. Again as detailed above I have it defaulting to ‘accountName’ which is index 5 in my list. Change (Line 77) for the default you want. This means you can just hit enter if accountName is what you’re querying on (which is common). Or choose another option. This then also allows you to also choose multiple attributes (which will be added to an array). This means you can use this for complex queries such as;

accountName startsWith 'dar'
sn startsWith 'rob'
mail contains '@kloud'

If you want to choose multiple attributes for your query and one of them is the default option, make sure you specify one of the attributes that is not the default first so that you get the option to specify more. When you’ve chosen all the attributes you are going to use in your query hit enter and the script will take an empty response as the end of your choices.

Now for each attribute chosen you will be prompted for an Operator. Pretty simple. Just choose from the available options. Note: all operators are shown but not all operators can be used for all attribute types. e.g. Don’t select ‘EndsWith’ for a Boolean attribute type and expect it to work. If you choose an operator other than the default (equals in my example) hit enter when prompted for the second time and the script will take an empty response as the end of your choices.

Finally provide what you the value is for the search term for the attribute. If the value has spaces, don’t worry about putting the value in quotes. The script takes care of that.

The last two steps will iterate through, for queries where you have chosen multiple attributes.

And you’re done. $query is the variable that contains the results. In line 115 I’m using Show-Object from the PowershellCookBook PSM. That then gives you a GUI representation of the result as shown below. If the query returns multiple results this will only show the last.

Line 114 outputs the value of the attributes ($query.attributes) to the console as well. If you have multiple objects returned $query will show them as shown below.

Finally if you want to run the query again, or just make a subtle change, you shouldn’t have to go through that again. Get the value of $querytxt and you’ll get the query and the command to execute it. $querytxt is also output to the console as shown below. Copy and paste it into Powershell ISE, update and execute.

The Script

Here is the raw script. Hardly any error handling etc, but enough to get you started and tailor it for your requirements. Enjoy.

Scripting the generation & creation of Microsoft Identity Manager Sets/Workflows/Sync & Management Policy Rules with the Lithnet Resource Management PowerShell Module

Introduction

Yes, that title is quite a mouthful. And this post is going to be quite long. But worth the read if you are having to create a number of rules in Microsoft/Forefront Identity Manager, or even more so the same rule in multiple environments (eg. Dev, Staging, Production).

My colleague David Minnelli introduced using the Lithnet RMA PowerShell Module and the Import-RMConfig cmdlet recently for bulk creation of MIM Sets and MPR’s. David has a lot of the background on Import-RMConfig and getting started with it. Give that a read for a more detailed background.

In this post I detail using Import-RMConfig to create a Set, Workflow, Synchronization Rule and Management Policy Rule to populate a Development AD Domain with Users from a Production AD Domain. This process is designed to run on a combined MIM Service/Sync Server. If your roles a separated (as they likely will be in a Production environment) you will need to run these scripts on the MIM Sync Server (so it can query the Management Agents, and you will need to add in a line to connect to the MIM Service (eg. Set-ResourceManagementClient ) at the beginning of the script.

In my environment I have two Active Directory Management Agents, each connected to an AD Forest as shown below.

On each of the AD MA’s I have a Constant Flow Attribute (named Source) configured to flow in a value representing the source AD Forest. I’m doing this in my environment as I have more than one production forest (hence the need for automation). You could simply use the Domain attribute for the Set criteria. That attribute is used in the Set later on. Mentioning it up front so it make sense.

Overview

The Import-RMConfig cmdlet uses XML and XOML files that contain the configuration required to create the Set, Workflow, Sync Rule and MPR in the FIM/MIM Service. The order that I approach the creation is, Sync Rule, Workflow, Set and finally the MPR.

Each of these objects as indicated above leverage an XML and/or XOML input file. I’ve simplified base templates and included them in the scripts.

The Sync Rule Script includes a prompt to choose a folder (you can create one through the GUI presented) to store the XML/XOML files to allow the Import-RMConfig to use them. Once generated you can simply reference the files with Import-RMConfig to replicate the creation in another environment.

Creating the Synchronization Rule

For creation of the Sync Rule we need to define which Management Agent will be the target for our Sync Rule. In my script I’ve automated that too (as I have a number to do). I’m querying the MIM Sync Server for all its Active Directory MA’s and then providing a dialog to allow you to choose the target MA for the Sync Rule. That dialog simply looks like the one below.

Creating the Sync Rule will finally ask you to give the Rule a name. This name will then be used as the base Display Name for the Set, MPR and Workflow (and a truncated version as the Rule ID’s).

The script below in the $SyncRuleXML section defines the rules of the Sync Rule. Mine is an Outbound Sync Rule, with a base set of attributes and transforming the users UPN and DN (for the differing Development AD namespace). Update lines 42 and 45 for the users UPN and DN your namespace.

Creating the Workflow

The Workflow script is pretty self-explanatory. A simple Action based workflow and is below.

Creating the Set

The Set is the group of objects that will be synchronized to the target management agent. As my Sync Rule is only for Users my Set is also only contains users. As stated in the Overview I have an attribute that defines the authoritative source for the objects. I’m also using that in my Set criteria.

Creating the Management Policy Rule

The MPR ties everything together. Here’s that part of the script.

Tying them all together

Here is the end to end automation, and the raw script that you could use as the basis for automating similar rule generation. The Sync Rule could easily be updated for Contacts or Groups. Remember the attributes and object classes are case sensitive’.

  • Through the Browse for Folder dialog I created a new folder named ProvisionDevAD

  • I provided a Display Name for the rules

  • I chose the target Management Agent

  • The SyncRule, Workflow, Set and MPR are created. The whole thing takes seconds.

  • Script Complete

Let’s take a look at the completed objects through the MIM Portal.

Sync Rule

The Sync Rule is present as we named it. Including the !__ prefix so it appears at the top of the list.

Outbound Sync Rule based on a MPR, Set and Workflow

The Resources will be created and if deleted de-provisioned.

And our base attribute flows.

Set

Our Set was created.

Our naming aligns with what we input

And a Criteria based Set. As per the Overview I have an attribute populated by a Constant flow rule that I based my set on. You’ll want to update for you environment.

Workflow

The Action Workflow was created

All looks great

And it applies our Sync Rule

MPR

And finally our MPR. Created as a Transition In MPR with Action Workflow

Set Transition and naming all aligned

The Transition Set configured for the Set that was created

And the Workflow configured with the Workflow that was just created

Summary

When you have a lot of Sync Rules to create, or you know you will need to re-create them numerous times, potentially in different environments automation is key. This just scratches the surface on what can be achieved, and made so much easier using the Lithnet PowerShell Modules.

Here’s is the full script. Note: You’ll need to make a couple of minor changes as indicated earlier, but you should be able to create a Provisioning Rule end to end pretty quick to validate the process. Then customize accordingly for your environment and requirements. Enjoy.

Automating Source IP Address updates on an Azure Network Security Group RDP Access Rule

Recently I’ve migrated a bunch of Virtual Box Virtual Machines to Azure as detailed here. These VM’s are in Resource Groups with a Network Security Group associated that restricts access to them for RDP based on a source TCPIP address. All good practice. However from a usability perspective, when I want to use these VM’s, I’m not always in the same location, and rarely on a connection with a static IP address.

This post details a simple little script that;

  • Has a couple of variables associated with a Resource Group, Network Security Group, Virtual Machine Name and an RDP Configuration File associated with the VM
  • Gets the public IP Address of the machine I’m running the script from
  • Prompts for Authentication to Azure, and retrieves the NSG associated with the Resource Group
  • Compares the Source IP Address in the ‘RDP’ Inbound Rule to my current IP Address. If they aren’t a match it updates the Source IP Address to be my current public IP Address
  • Starts the Virtual Machine configured at the start of the script
  • Launches Remote Desktop using the RDP Configuration file

The Script

Here’s the raw script. Update lines 2-8 for your environment and away you go. Simple but useful as is often the way.
