Set your eyes on the Target!

1015red_F1CoverStory.jpg

So in my previous posts I’ve discussed a couple of key points in what I define as the basic principles of Identity and Access Management;

Now that we have all the information needed, we can start to look at your target systems. Now in the simplest terms this could be your local Active Directory (Authentication Domain), but this could be anything, and with the adoption of cloud services, often these target systems are what drives the need for robust IAM services.

Something that we are often asked as IAM consultants is why. Why should the corporate applications be integrated with any IAM Service, and these are valid questions. Sometimes depending on what the system is and what it does, integrating with an IAM system isn’t a practical solution, but more often there are many benefits to having your applications integrated with and IAM system. These benefits include:

  1. Automated account provisioning
  2. Data consistency
  3. If supported Central Authentication services

Requirements

With any target system much like the untitled1IAM system itself, the one thing you must know before you go into any detail are the requirements. Every target system will have individual requirements. Some could be as simple as just needing basic information, first name, last name and date of birth. But for most applications there is allot more to it, and the requirements will be derived largely by the application vendor, and to a lessor extent the application owners and business requirements.

IAM Systems are for the most part extremely flexible in what they can do, they are built to be customized to an enormous degree, and the target systems used by the business will play a large part in determining the amount of customisations within the IAM system.

This could be as simple as requiring additional attributes that are not standard within both the IAM system and your source systems, or could also be the way in which you want the IAM system to interact with the application i.e. utilising web services and building custom Management Agents to connect and synchronise data sets between.

But the root of all this data is when using an IAM system you are having a constant flow of data that is all stored within the “Vault”. This helps ensure that any changes to a user is flowed to all systems, and not just the phone book, it also ensures that any changes are tracked through governance processes that have been established and implemented as part of the IAM System. Changes made to a users’ identity information within a target application can be easily identified, to the point of saying this change was made on this date/time because a change to this persons’ data occurred within the HR system at this time.

Integration

Most IAM systems will have management agents or connectors (the phases can vary depending on the vendor you use) built for the typical “Out of Box” systems, and these will for the most part satisfy the requirements of many so you don’t tend to have to worry so much about that, but if you have “bespoke” systems that have been developed and built up over the years for your business then this is where the custom management agents would play a key part, and how they are built will depend on the applications themselves, in a Microsoft IAM Service the custom management agents would be done using an Extensible Connectivity Management Agent (ECMA). How you would build and develop management agents for FIM or MIM is quite an extensive discussion and something that would be better off in a separate post.

One of the “sticky” points here is that most of the time in order to integrate applications, you need to have elevated access to the applications back end to be able to populate data to and pull data from the application, but the way this is done through any IAM system is through specific service accounts that are restricted to only perform the functions of the applications.

Authentication and SSO

Application integration is something seen to tighten the security of the data and access to applications being controlled through various mechanisms, authentication plays a large part in the IAM process.

During the provisioning process, passwords are usually set when an account is created. This is either through using random password generators (preferred), or setting a specific temporary password. When doing this though, it’s always done with the intent of the user resetting their password when they first logon. The Self Service functionality that can be introduced to do this enables the user to reset their password without ever having to know what the initial password was.

Depending on the application, separate passwords might be created that need to be managed. In most cases IAM consultants/architects will try and minimise this to not being required at all, but this isn’t always the case. In these situations, the IAM System has methods to manage this as well. In the Microsoft space this is something that can be controlled through Password Synchronisation using the “Password Change Notification Service” (PCNS) this basically means that if a user changes their main password that change can be propagated to all the systems that have separate passwords.

SONY DSCMost applications today use standard LDAP authentication to provide access to there application services, this enables the password management process to be much simpler. Cloud Services however generally need to be setup to do one of two things.

  1. Store local passwords
  2. Utilise Single Sign-On Services (SSO)

SSO uses standards based protocols to allow users to authenticate to applications with managed accounts and credentials which you control. Examples of these standard protocols are the likes of SAML, oAuth, WS-Fed/WS-Trust and many more.

There is a growing shift in the industry for these to be cloud services however, being the likes of Microsoft Azure Active Directory, or any number of other services that are available today.
The obvious benefit of SSO is that you have a single username or password to remember, this also greatly reduces the security risk that your business has from and auditing and compliance perspective having a single authentication directory can help reduce the overall exposure your business has to compromise from external or internal threats.

Well that about wraps it up, IAM for the most part is an enabler, it enables your business to be adequately prepared for the consumption of Cloud services and cloud enablement, which can help reduce the overall IT spend your business has over the coming years. But one thing I think I’ve highlighted throughout this particular series is requirements requirements requirements… repetitive I know, but for IAM so crucially important.

Synchronizing Passwords from Active Directory to the IBM/Lotus Domino Identity Vault using Microsoft Identity Manager – Part 3

Introduction

As the title suggests this is Part 3, and the final part in a three-part post on configuring FIM/MIM to synchronise users passwords from AD to the Domino ID Vault via PCNS and FIM/MIM.
Part 1 here detailed the creation of a PowerShell Management Agent to join users from Domino to the MIM Sync Metaverse.
Part 2 here detailed the creation and configuration of the Domino Agents to receive password changes via the PS MA into the ID Vault.

This post will wrap it all up with the details on calling the Domino Agents on password sync events (from PCNS via MIM)

Prerequisites

You will need the IBM Notes client installed and configured on your MIM Sync Server in order to put a document in the database we created in Part 2 and start the agent to process the document(s).

Overview

Essentially this is the process;

  • Password changed for a user (either by an admin, or by the user via their domain joined workstation, password reset or any other password change mechanism)
  • Password change is captured by the AD PCNS Filter installed and configured on each (writeable) Domain Controller
  • The DC using the PCNS Config in the domain locates the MIM Sync Server to send the password change too
  • The MIM Sync Server has the associated AD Domain configured as a Password Sync Source
  • Our new PowerShell ID Vault Notes MA is configured as a Password Target
  • MIM Sync passes off the password change event for MIM joined users to the ID Vault Password Change MA which initiates the Password.ps1 script (below)
  • The password.ps1 script creates a document (that contains the details for the password change) in our ID Vault Password Sync Database we created in Part 2 of this series and then tells the MIMPwdTrigger Agent to start
  • The MIMPwdTrigger Agent picks up the document, passes it to the MIMPasswordSync Agent which sends the password change to the ID Vault

Domino PowerShell Management Agent Password.ps1 Script

Put this Password.ps1 script in the same location you put the Schema, Import and Export scripts earlier.

Testing Password Sync End to End (Active Directory to the ID Vault)

The following screen shots show me tracing through the logs for a password change as it makes it way from the AD Domain Controller to MIM Sync to the MA to the MA Password script to the Notes DB as a document triggered to be process by the Notes Agent and the user updated in the ID Vault.

First the password change event is initiated to the MIM Sync Service by the Domain Controller that captured the password change.

PCNS provides all the details for the password change.

The MIM Sync Server determines where to send the change which includes our PS Notes MA.

Our PS Notes MA logged the process.

Notes MA LOG

=============================================================

Display Name: Jane XXX/xxx/xxxxx-Aus

Action: Set

Old pwd:

New pwd: Password123456

As did the Notes Agent as it process the change.

MIMPasswordSync|mimpasswordsync: 08/03/2017 02:56:23 PM: Removed User ID Vault change document from ‘xxxNotes1/xxxxx-Aus’

And finally we see the change reflected in the ID Vault. Looking at the time-stamps along the way we see that it all happened in approximately 2 seconds.

Summary

This three-part blog post has shown how to get passwords from Active Directory to the MIM Sync connected source across to IBM Domino and into the ID Vault using the Granfeldt PowerShell Management Agent and some configuration with a Database in Domino with two Domino Agents.

What have you synchronised passwords too using FIM/MIM ?

UPDATED: Identifying Active Directory Users with Pwned Passwords using Microsoft/Forefront Identity Manager

Earlier this week I posted this blog post that showed a working example of using a custom Pwned Password FIM/MIM Management Agent to flag a boolean attribute in the MIM Service to indicate whether a users password is in the pwned password dataset or not. If you haven’t read that post this won’t make a lot of sense, so read that then come back.

The solution when receiving a new password for a user (via Microsoft Password Change Notification Service) was checking against the Have I Been Pwned API. The disclaimer at the start of the blog post detailed why this is a bad idea for production credentials. The intent was to show a working example of what could be achieved.

This update post shows a working solution that you can implement internal to a network. Essentially taking the Pwned Password Datasets available here and loading them into a local network SQL Server and then querying that from the FIM/MIM Pwned Password Management Agent rather than calling the external public API.

Creating an SQL Server Database for the Pwned Passwords

On my SQL Server using SQL Server Management Studio I right-clicked on Databases and chose New Database. I gave it the name PwnedPasswords and told it where I wanted my DB and Logs to go to.

Then in a Query window in SQL Server Management Studio I used the following script to created a table (dbo.pwnedPasswords).

use PwnedPasswords;
 CREATE TABLE dbo.pwnedPasswords
( password_id int NOT IDENTITY(1,1) NULL,
 passwords varchar(max) NOT NULL,
 CONSTRAINT passwords_pk PRIMARY KEY (password_id)
);

Again using a query window in SQL Server Management Studio I used the following script to create an index for the passwords.

USE [PwnedPasswords]USE [PwnedPasswords]
GO
SET ANSI_PADDING ON

GO
CREATE UNIQUE NONCLUSTERED INDEX [PasswordIndex] ON [dbo].[pwnedPasswords]( [password_id] ASC)INCLUDE ( [passwords]) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON)
GO

The last thing I did on the DB was to take the MIM Sync Server Active Directory Service Account (that was already in the SQL Server Logins) and give that account Reader Access to my new PwnedPasswords Database. I gave this account access as I’m using Integrated Authentication for login to SQL and as the MA is initiated by the MIM Sync Service Account, that is the account that needs the access.

Getting the Pwned Password Datasets into the new Database

I’m far from a DBA. I’m an identity guy. So using tools I was most familiar with (PowerShell) I created a simple script to open the password dump files as a stream (as Get-Content wasn’t going to handle the file sizes), read in the lines, convert the format and insert the rows into SQL. I performed the inserts in batches of 1000 and I performed it locally on the SQL Server.

In order to get the content from the dump file, add another column and get it in a format quickly to insert into the SQL DB I used the Out-DataTable function available from here.

The script could probably be improved as I only spend about 20-30 minutes on it. It is opening and closing a connection to the SQL DB each time it inserts 1000 rows. That could be moved outside the Insert2DB Function and maybe the batch size increased. Either way it is a starting point and I used it to write millions of rows into the DB successfully.

Updated FIM/MIM Pwned Passwords Management Agent Password.ps1 script

This then is the only other change to the solution. The Password.ps1 script rather than querying the PwnedPasswords API queries the SQL DB and sets the pwned boolean flag accordingly.

Summary

This enhancement shows a working concept that will be more appealing to Security Officers within corporate organisations if you have an appetite to know what your potential exposure is based on your Active Directory Users Passwords.

Synchronizing Passwords from Active Directory to the IBM/Lotus Domino Identity Vault using Microsoft Identity Manager – Part 2

Introduction

As the title suggests this is Part 2 of a three-part post on configuring FIM/MIM to synchronise users passwords from AD to the Domino ID Vault via PCNS and FIM/MIM.
Part 1 here detailed the creation of a PowerShell Management Agent to join users from Domino to the MIM Sync Metaverse.

This post details the creation and configuration of the Domino Agents to receive password changes via the PS MA into the ID Vault.

Part 3 here  details calling the Domino Agents on password sync events (from PCNS via MIM)

Creating a New Domino Application

As mentioned above and in Part 1 we need to create Domino Agents to process password change events into the ID Vault. Domino Agents are required as Domino security will not allow password change events (called using the resetUserPassword method) to be run remotely.  The resetUserPassword method is only supported using the RunOnServer method.

In order to create a Domino Agent we need to install and run the IBM Domino Designer.

With that installed we can start with our first Domino Agent. We will create two Agents. The first will be the one that will perform the execution of the resetUserPassword method. The second will be the trigger that will retrieve the details of the user to change the password for and pass it to the first agent to execute.

In IBM Domino Designer select File => New => Application

Specify the Server to create the new Application on (and subsequently where it will run) and give the Application a name. I used ID Vault PWD Sync.

Create the MIM Password Sync Domino Agent

With the New Application created we can navigate to Code => Agents and select New Agent

Give the Agent a name. I named this one MIMPasswordSync and make sure the type is Java

With the Agent created we need to give it the script that will perform the password changes. Double click on the agent then in the Agent Contents double-click on JavaAgent.java and paste in the script (from Github further below). The only change you may need to make is the location where you want the logging to go to. You will need to create that path if it doesn’t exist as well.

Selecting the Agent Tab in the main pain locate the Agent Properties and configure as per the screenshot below.

Select the Security Tab in the Properties pane and set the Runtime security level to 3. If the options are blanked out and you can’t select them, close the agent and re-open it and you will be able to configure this option.

Create the MIM Password Trigger Domino Agent

Create the MIM Password Trigger Domino Agent just as you did the MIM Password Sync Domino Agent. Name it MIMPwdTrigger and make sure the type is also Java. Double click on the Agent and then double-click on JavaAgent.java in the Agent Contents. Use the following script. Note it calls the MIMPasswordSync Agent so if you called yours something different you will need to change it in this script (line 12).

Select the MIMPwdTrigger Agent in the main pane and look at the Properties. Make Runtime to be On event and After documents are created or modified. 

Select the Security Tab in the Properties pane and set the Runtime security level to 3. If the options are blanked out and you can’t select them, close the agent and re-open it and you will be able to configure this option

Configuration ID Vault Password Reset Authority

In order for our MIMPasswordSync Agent to actually change users passwords in the ID Vault we need to configure the ID Vault to allow the account that created and signs the Agents and the Server that the Agents will run on to be Trusted Password Reset Authorities.

Using the IBM Domino Administrator select the Administration menu item and then Configuration. Expand Security from the left hand pane and select ID Vaults.

Having selected the ID Vault from the main pane you will be changing passwords in, on the right hand menu pane expand ID Vaults and double-click on Password Reset Authority.

From the Password reset authority by organisation box select the OrgU/Org you will be sync’ing passwords too. If you have many you will need to complete this step for each one. You will need to do one OrgU/Org at a time if they have different certifiers.

From the Available users, groups and servers box select the Server that you run the Agents with, and select Add. Repeat for selecting the user that you created the Agents with and that will sign the Agents. Then select the user you just added in the Password reset authority by organisation and then select the Password reset agent authority checkbox.  That will put the red @ symbol on the user which identifies it as a Password Reset Agent Authority.

Select Next/Configure, locate the certifier ID for that OrgU/Org, provide the password and complete the process. Repeat for each OrgU/Org.

Signing the Agents

Back using the Domino Designer double-click Agents in the left menu pane. Select each Agent and then click Sign.

Creating a Form to test the Agents

Now we will create a form to allow us to create a document in the DB easily and test that our agents work. In Domino Designer, right-click on Forms and select New Form.

Give the Form a name and an alias. It doesn’t matter what you call it. We’re just using it to test the agents.

Double Click on your new Form. Click in the empty pane and then from the Create menu select Field. Name it server. Repeat for another field and name it username.

Repeat for the third text field, but name it password and select the Type Password.

Finally from the Create menu select Hotspot => Button. Name it Submit and then select it. In the Properties of the button for Run select Client. For Formula enter the formula below.

@Command([FileSave]);
@Command([FileCloseWindow]);
@Command([ToolsRunMacro];"MIMPwdTrigger")

Testing the Agents

In the Domino Designer right-click on the form and select Preview in Notes.

The format for the fields is;

  • server: Server/Org
  • user: Joe Smith/OrgU/Org
  • password: P@SSw0rd

Enter valid input for your environment.

And click on the Submit button. If you have everything correct the document you just created will be processed by the Trigger Agent and then the MIM Password Sync Agent.

If there is an error you will likely have a document still in the IDVault PWD Sync database as shown below. Check the document to make sure you got the details for the user and server correct.

Also check the log file. C:\PWDSync\AgentLog.txt by default as per the script path. When working correctly you will see an entry as per below. If it wasn’t successful the error message should point you to where you have gone wrong. More than likely different names for the Agents, or incorrect format or name for the user and/or server. Or Trusted Password Authority not set for the account the agent was signed with to the OrgU/Org containing the user you are trying to change a password for.

MIMPasswordSync|mimpasswordsync: 08/08/2017 02:08:24 PM: Reseting password ...
MIMPasswordSync|mimpasswordsync: 08/08/2017 02:08:24 PM: Server: XXXNotes1 User:Jane Doe/OrgU/Org-Aus
MIMPasswordSync|mimpasswordsync: 08/08/2017 02:08:26 PM: Return value: true
MIMPasswordSync|mimpasswordsync: 08/08/2017 02:08:26 PM: Removed User ID Vault change document from 'XXXNotes1'

Summary

Now that we have our Agents built and working we need to be able to call them from our MIM Sync Server. That will be covered in the third and final post in this series.

Synchronizing Passwords from Active Directory to the IBM/Lotus Domino Identity Vault using Microsoft Identity Manager – Part 1

Introduction

Recently I wrote about getting started with the latest IBM/Lotus Notes/Domino Management Agent for Microsoft Identity Manager. In a recent engagement we are using that MA to provision and manage identities into Domino. We are also using the MA to synchronise passwords via PCNS and MIM to the Notes users’ Internet (HTTP) password.

What you may or may not be aware of is that IBM introduced a new feature with Domino 8.5 called the ID Vault. The ID Vault is a Domino based application that holds protected copies of Notes user IDs. Now here’s the twist. The Microsoft Domino MA only supports password synchronisation to the HTTP password, not to the ID Vault.

My customer is using the ID Vault and naturally we need to synchronise password changes to both the HTTP Password and the ID Vault (for users Notes IDs). This post is the first in a series that details how I recently accomplished synchronising passwords to the Domino ID Vault.

  1. This post provides the introduction and the creation of a PowerShell Management Agent into Domino to join identities into the MIM Metaverse
  2. Post two details Creating Domino Agents that will handle taking requests from the MIM PS MA to change users ID Vault password
  3. Post three will detail calling the Domino Agents on password sync events (from PCNS via MIM)

Overview

The following diagram shows a high-level overview of password synchronisation using FIM/MIM from AD to Domino. Password changes/resets can be initiated using a number of methods. The FIM/MIM Self Service Password Reset functionality, users changing their password via their domain joined workstations as defined by AD Group Password Polic(y)ies, using the AD FS Password Change function, or even on behalf of users by a Service Desk/Administrator. In each scenario implementing Microsoft’s Password Change Notification Service will get the password change to FIM/MIM. I’m not going to cover PCNS as it is out of the box and straight forward to install and configure. This MS PFE PCNS implementation document covers it quite well.

Likewise I’m not going to go into any detail about password sync to the HTTP Password. That’s out of the box functionality, that is pretty much the same as any other MA configured as a Password Sync Target. That said in my environment I did have to configure the MS Domino MA like this to get password events out to Domino.

ID Vault FIM/MIM PowerShell Management Agent

First up, we are going to need a Management Agent to join Notes users to our users from Active Directory in the Metaverse. I’ve gone to my favourite PowerShell Management Agent (Granfeldt) for this.

The Granfeldt PS MA will be configured to;

  • Import and join Domino Users to the Metaverse. The MA will be slimline in the number of attributes it brings in. Enough to perform the join and have enough information about the users context in Domino to be able to perform the password sync event
  • be a target for Password Synchronisation
  • send the password change event to the Domino Agent we will build to perform the password change. A Domino Agent is required as the ID Vault will only accept password changes from a process run on the Domino Server(s). More on this in parts 2 and 3

The integration of the MIM Sync Engine with Domino with the PowerShell Management Agent is done using LDAP. The Name and Address Book is easily accessed via LDAP.

To get started I looked up the Server Document for the Domino Server I wanted to connect to that had the Name and Address Book. Selecting the Directory tab I could see that LDAP(S) 389/636 was enabled.

I then went to the Name and Address Book and looked up my Admin Notes ID to get its context so I could translate it to LDAP format. Darren Kloud Robinson/OrgU/Org-AUS translates to CN=Darren Kloud Robinson,OU=Org,O=Org-AUS“.

Knowing my Notes ID Password I used LDP from Windows Server to bind to the Domino Directory. You could use any LDAP Browser/Tool.

Once I validated I could connect and browse the tree, I knew I had my connection details sorted, I translated that to PowerShell.

That looked something like this;

I then wrapped this into a FIM/MIM PowerShell Management Agent. The Granfeldt PS MA Scripts are below.

Domino PowerShell Management Agent Schema Script

As described above the Schema Script is very light on the number of attributes specified. Basically the minimum required to get a join and give us the context of the user to process password sync events.

Domino PowerShell Management Agent Import Script

As detailed above the Import brings through enough metadata to perform the join and give us the attributes needed for the user context to be able to sync passwords through.

Domino PowerShell Management Agent Export Script

File just needs to exist. Not used in this scenario.

Domino PowerShell Management Agent Password Script

See Part 3 in this series for the Password.ps1 script. But if you are following sequentially, copy the empty Export.ps1 script for now and name it Password.ps1 and have it located in the same directory as the other PS MA scripts.

Wiring it all together

As for creating the PS MA, I’ve detailed this in-depth many times. Check out this post (or the many other similar I’ve posted) and the Getting Started section if you are new to the Granfeldt PowerShell Management Agent. Copy the above scripts to the directory you create, and when creating the MA provide the paths to the scripts (in 8.3 format).

A key item though is to configure the PS MA as a Password Sync Target as per the screenshot below. You will also need to configure where passwords are coming from to send to this new MA. If it is Active Directory, open the Properties of your AD MA select Configure Directory Partitions then under Password Synchronization enable the checkbox Enable this partition as a password synchronization source. Select Targets and select your newly created Notes ID Vault Password MA. Select Ok then Ok again.

After creating a Run Profile and doing a Stage and Import, based on your Join rule (probably email address) you should have a heap of connectors. In my environment displayName contains the context of the user. Eg. Full Name/OrgU/Org We’ll need this to send the password change event to the ID Vault.

Summary

Through the PowerShell MA as detailed above we have been able to enumerate users from Domino and join them to existing users in the MIM Sync Metaverse. We can now set about creating Domino Agents to take password sync events from this MA and change users passwords in the Domino ID Vault.

Part 2 in this series here details creating the Domino Agents and configuring Domino to accept the changes.

Identifying Active Directory Users with Pwned Passwords using Microsoft/Forefront Identity Manager

Update: An element of this solution details checking passwords online (using the Have I Been Pwned API). Troy explains succinctly in his blog-post announcing the pwned passwords list why this is a bad idea. If you are looking to implement the concept I detail in this post then WE STRONGLY recommend using a local copy of the pwned password list.
THIS POST HERE details using a local SQL Database to hold the Pwned Passwords Datasets and the change to the Management Agent to query the SQL DB instead of the HIBP API.  

Introduction

Last week (3 Aug 2017) Troy Hunt released a sizeable list of Pwned Passwords. 320 Million in fact. I encourage you strongly to have a read about the details here.

Troy also extended his HaveIBeenPwned API to include the ability to query as to whether a password has been pwned and is likely to be used in a brute force attack.

Microsoft provide a premium license feature in Azure Active Directory (Azure Active Directory Identity Protection) whereby leaked credential sets are checked and Admins alerted via reports. But what if you aren’t licensed for the Azure AD Premium Features, or you want something a little more customised and you have Microsoft/Forefront Identity Manager? That is what this post covers.

Overview

The following diagram looks a little more complicated than what it really is. The essence though is that password changes can come from a multitude of different scenarios. Using Microsoft’s Password Change Notification Service (PCNS) we can capture password changes and send them to Microsoft Identity Manager so that we can synchronise the password to other systems, or for this use case we can lookup to see if the users new password is on the pwned password list.

This post will cover creating the Pwned Password FIM/MIM Management Agent and flagging a boolean attribute in the MIM Service to indicate whether a users password is on the pwned password or not.

PwnedPassword Overview.png

Prerequisites

There are a few components to this solution depicted above. You will need;

  • FIM/MIM Synchronisation Server
    • with an Active Directory Management Agent configured (most likely you will have a Projection Rule on this MA to get your users into the Metaverse)
    • not shown in the diagram above you will also need the MIM MA configured to sync users from the Metaverse to the MIM Service
  • FIM/MIM Service and Portal Server (can be on the same server as above)
  • Microsoft Password Change Notification Service (PCNS). This MS PFE PCNS implementation document covers it quite well and you will need;
    • the PCNS AD Schema Extension installed
    • the PCNS AD Password Filters installed on all your (writeable) Domain Controllers
    • PCNS configured to send password changes to your FIM/MIM Sync Server
  • Granfeldt PowerShell Management Agent (that we will use to check users passwords against the Have I Been Pwned pwned password API)
  • Lithnet Resource Management PowerShell Module
    • download it from here and install it on your FIM/MIM Server as the Pwned Password MA will use this module to populate the Pwned Password Status for users in the MIM Service
  • Windows Management Framework (PowerShell) 5.x

Getting Started with the Granfeldt PowerShell Management Agent

If you don’t already have it go get it from here. Søren’s documentation is pretty good but does assume you have a working knowledge of FIM/MIM and this blog post is no different.

Four items of note for this solution;

  • You must have an Export.ps1 file. Even though we’re not doing exports on this MA, the PS MA configuration requires a file for this field. The .ps1 doesn’t need to have any logic/script inside it. It just needs to be present
  • The credentials you give the MA to run this MA are the credentials for the account that has permissions to the On Premise Active Directory where we will be importing users from to join to our Metaverse so we can pass password changes to this Management Agent
  • The same account as above will also need to have permissions in the MIM Service as we will be using the account to update the new attribute we are going to create
  • The path to the scripts in the PS MA Config must not contain spaces and be in old-skool 8.3 format. I’ve chosen to store my scripts in an appropriately named subdirectory under the MIM Extensions directory. Tip: from a command shell use dir /x to get the 8.3 directory format name. Mine looks like C:\PROGRA~1\MICROS~4\2010\SYNCHR~1\EXTENS~2\PwnedPWD

With the Granfeldt PowerShell Management Agent downloaded from Codeplex and installed on your FIM/MIM Server we can create our Pwned Password Management Agent.

Creating the Pwned PowerShell Management Agent

On your FIM/MIM Sync Server create a new sub-directory under your Extensions Directory. eg. PwnedPWD in C:\Program Files\Microsoft Forefront Identity Manager\2010\Synchronization Service\Extensions then create a sub-directory under PwnedPWD named DebugC:\Program Files\Microsoft Forefront Identity Manager\2010\Synchronization Service\Extensions\PwnedPWD\Debug

Copy the following scripts (schema.ps1, import.ps1, export.ps1, password.ps1) and put them into the C:\Program Files\Microsoft Forefront Identity Manager\2010\Synchronization Service\Extensions\PwnedPWD directory

Schema.ps1

The following schema.ps1 script sets up the object class (user) and a handful of attributes from Active Diretory that will be useful for logic that we may implement in the future based on users password status.

Import.ps1

The import.ps1 script connects to Active Directory to import our AD users into the Pwned Password Management Agent so we can join to the Metaverse object already present for users on the Active Directory Management Agent. The user needs to be joined to the Metaverse on our new MA so they are addressable as a target for PCNS.

Export.ps1

As detailed earlier, we aren’t using an Export script in this solution.

Password.ps1

The Password script receives password changes as they occur from Active Directory and looks up the Have I Been Pwned API to see if the new password is present on the list or not and sets a boolean attribute for the pwned password status in the MIM Service.

On your FIM/MIM Sync Server from the Synchronisation Manager select Create Management Agent from the right hand side pane.  Select PowerShell from the list of Management Agents. Select Next.

PwnedPwdMA1a

Give your MA a Name and a Description. Select Next.

PwnedPwdMA10

Select Next.

PwnedPwdMA11

Ensure that Enabled password management is selected, then select Finish.

PwnedPwdMA12

With the Pwned Password MA created and configured we need to create at least a Stage (Full Import) and Full Sync Run Profiles and execute them to bring in the users from AD and join them to the Metaverse.

This should be something you’re already familiar with.

RunProfiles

When running the Synchronisation we get the joins we expect. In my environment PwdLastSet was configured to sync to the MIM Service and hence the Outbound Sync to on the MIM Service MA.

Sync and join

MIM Service Configuration

In the MIM Service we will create a custom boolean attribute that will hold the pwned status of the users password.

Schema

Connect to your MIM Portal Server with Administrator privileges and select Schema Management from the right hand side menu.

Select All Attributes then select New

Provide an attribute name (System name) and a Display Name with a Data Type of Boolean. Provide a Description and select Finish

Select Submit

Search for User in Resource Types then select the User checkbox from the search results and select Binding then select New.

In the Resource Type box type User then click the validate field button (the one with the green tick). In the Attribute Type box type Pwned Password then click the validate field button (the one with the green tick). Select Finish

Select  Submit

Configure the Active Directory MA to send passwords to the Pwned Passwords MA

On your existing Active Directory Management Agent select Properties. Select Configure Directory Partitions then under Password Synchronization enable the checkbox Enable this partition as a password synchronization source. Select Targets and select your newly created Pwned Password MA. Select Ok then Ok again.

Testing the End to End Pwned Password Check

Now you should have configured;

  • PCNS including installation of the Active Directory filters
  • The existing Active Directory Management Agent as a Password Source
  • The existing Active Directory Management Agent to send password change events to the Pwned Password MA

Select a user in Active Directory Users and Computers, right click the user and select Reset Password.

ChangePassword1

I first provided a password I know is on the pwned list, Password1

ChangePassword2

ChangePassword3

With PCNS Logging enabled on the MIM Sync Server I can see the password event come through.

ChangePassword4

Checking in the Pwned Password MA debug log we can see in the debug logging for the user we changed the password for and that when it was checked against Have I Been Pwned the password is flagged as pwned.

Note: If you implement the solution in a production environment obviously remove the password from being logged. 

ChangePassword5

In the MIM Portal search for and locate the user the password we just changed the password for.

ChangePassword7.PNG

Select the user. Scroll to the bottom and select Advanced View. Select the Extended Attributes tab. Scroll down and we can see the Pwned Password shows as checked.

ChangePassword6

Now repeating the process with a password that isn’t in the Pwned Password list. After changing the password in Active Directory Users and Computers the password went through its sync path. The log shows the password isn’t in the list.

ChangePassword8

And the MIM Portal shows the Boolean value for Pwned Password is now not selected.

ChangePassword9

Summary

Using PCNS and FIM/MIM we can check whether our Active Directory users are using passwords that aren’t in the Pwned Password list.

What we can then do if their password is in the Pwned Password list is a number of things based on what the security policy is and even what type of user it is. You’ll notice that I’ve included additional attributes in the MA that we can flow through the Metaverse and into the MIM Service that may help with some of those decisions (such as adminCount which indicates if the user is an Administrator).

Potentially for Admin users we could create a workflow in the MIM Service that forces their account to change password on next logon. For other users we could create a workflow that sends them a notification letting them know that they should change their password.

Either way, we now have visibility of the state of users passwords. Big thanks to Troy for adding Pwned Passwords to his Have I Been Pwned API.

 

Reiterating: An element of this solution details checking passwords online (using the Have I Been Pwned API). Troy explains succinctly in his blog-post announcing the pwned passwords list why this is a bad idea. If you are looking to implement the concept I detail in this post then WE STRONGLY recommend using a local copy of the pwned password list.  

Error Synchronising passwords to users IBM/Lotus Domino HTTP Password with FIM/MIM – System.NotImplementedException: The method or operation is not implemented

Recently I posted about implementing the Microsoft IBM/Lotus Domino Management Agent.

In the implementation I needed to synchronise password changes from Active Directory to Lotus Notes (HTTP Password).  After configuring PCNS to send password change events to the FIM/MIM server, and configuring the IBM Domino MA as a password target I was hoping everything would just fire up like it normally does with PCNS.

However on a “password change event” I encountered the following error in the FIM/MIM Event Log.

The password management extension encountered an error.
 The stack trace is:
 
 "System.NotImplementedException: The method or operation is not implemented.
 at Microsoft.IdentityManagement.MA.LotusDomino.LotusDominoMA.GetConnectionSecurityLevel()
Forefront Identity Manager 4.4.1302.0"

and subsquently

A password synchronization set operation has failed in a target connected data source. 
 
Additional information:

Troubleshooting the issue I worked out that if I disabled the default of “Require secure connection for password synchronization operations” on the IBM Notes Management Agent as per the screenshot below, then everything works as expected.

Maybe this is due to a configuration option in the Domino environment I’m connecting too, or not. I’m not sure, but this got it working.

I’d love to check that box again, so if anyone else has an explanation for why/how I’d love to hear it.

Resolving Microsoft Identity Manager “sync-rule-validation-parsing-error” error

A couple of weeks back I inherited a Microsoft Identity Manager development environment that wasn’t quite complete. When I performed a sync on a user object I got the following error;  sync-rule-validation-parsing-error

Looking into the error for further details, Details and Stack Trace were both greyed out as shown below.

I looked at the object being exported on the MA and the awaiting export details and found slightly different information. The error was CS to MV to CS synchronization failed 0x8023055a 

Still not a lot to go on. So I looked in the Application Event Log and nothing. Anything in the System Event Log? No, nothing.

So my attention turned to the Export Synchronization Rule. Here is a partial screenshot of the Export Sync Rule. The object (user) in question had been flagged as inactive and the intent appeared to be a clearing of a number of attributes. Sending “” (crude empty/null) to an attribute isn’t very elegant.

I changed each to use the null function. So for export, null() will flow to each of the attributes. I tried the export again and the same error and problem resulted.

Running short on ideas I created a brand new Export Synchronization Rule and replicated the configuration except for the attributes being exported. Then I added one attribute into the rule at a time, tested the export and repeated until I could replicate the error.

I was able to replicate the error once I hit the terminalServer attribute.
*Note: the screenshot below is prior to changing over to flow null() instead of “”.

Sending null() to the terminalServer Active Directory attribute was causing the error. It was at this point I actually just removed that flow rule and continued with other tasks.

Coming back to this later, and thinking it through I understand the error. When dealing with Terminal Services you actually normally manage four attributes that are part of the userParameters attribute. The four attributes that define a users Terminal Services Profile are;

  • allowLogon
  • terminalServicesHomeDirectory
  • terminalServicesProfilePath
  • terminalServicesHomeDrive

For a user that has a fully configured set of Terminal Services attributes, sending null() to the terminalServer attribute isn’t going to work.

So, posting this as I couldn’t find any reference to sync-rule-validation-parsing-error or CS to MV to CS synchronization failed 0x8023055a elsewhere and chances are I’ll come across it again, and it’ll probably help someone else too.

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>"

MIM/FIM Full Sync of select objects only

As I detailed in my previous blog here, sometimes there is a need to perform a full synchronization of just a select set of objects in the MIM/FIM Synchronization Service. In my case, it was to all the Synchronization Rules which helped resolve my issue which required a selected Full Synchronization performed. For this customer’s FIM environment, I manually performed the Preview/Full Synchronization on 51 objects as I just needed it done. My colleague Darren Robinson suggested I look at scripting it using the ‘Lithnet PowerShell Module for FIM/MIM Synchronization Service’ located here. Up until this point, I hadn’t used this module in anger and I dearly wished I did as it would have saved plenty of time!

Ryan Newington has done a tremendous job with his modules released to the community to make our lives easier. He even enhanced the tool recently to make this particular task easier (note: make sure you grab the latest version, at least version v1.0.6351, as the script below will not work if you have an older version). The script I now regularly use on my customer’s large FIM environment after making changes to Synchronization Rules, where I mentioned in my previous blog we struggle for the opportunity to perform a Full Synchronization of the entire sync engine rule base, serves my purpose for Synchronization Rules, but you can easily modify the search criteria to perform a Full Synchronization of the objects you require. Here is the script and leave a comment if it has helped you.
