Using Password Synchronization

  • Artigo

To use password synchronization, you must configure the Active Directory domain, the management agents that connect to the target data sources to be managed for password synchronization, and the server running Microsoft® Forefront Identity Manager (FIM) 2010 R2. For general information about password synchronization, see Password Management. For a detailed password synchronization Step by Step Guide, see the Microsoft Web site.(https://www.microsoft.com/)

Configuring the domain controller

Install the password change notification service (PCNS)

The PCNS components must be installed on each Active Directory domain controller in the Active Directory domain that is participating in password synchronization. If the PCNS is not installed and running on an Active Directory domain controller, then any password changes that originate on that Active Directory domain controller are not synchronized with FIM. Running the file Password Change Notification Service.msion each Active Directory domain controller installs the following components:

Component Installed to folder

Password change notification service (Pcnssvc.exe)

\Program Files\Microsoft Password Change Notification

Password change notification configuration utility (Pcnscfg.exe). For more information, see Pcnscfg: Password Change Notification Service (PCNS) Configuration Utility

\Program Files\Microsoft Password Change Notification

Password change notification filter (Pcnsflt.dll)

%systemroot%\system32

Important

During the PCNS installation, the Active Directory schema is verified to ensure that classes and attributes needed to run the PCNS are available. If not, you are prompted to log on as a member of the Schema Admins group, and run the following: MSIEXEC.EXE /i "Password Change Notification Service.msi" SCHEMAONLY=TRUE. This extends the Active Directory schema with object classes and attributes needed to install and configure the PCNS. The schema only needs to be extended once for each Active Directory forest. The schema modifications are replicated to all other domain controllers. These attributes are not configured to be stored in the global catalog or indexed. The following classes and attributes are added during the schema extension:

Note

If you are installing the PCNS on multiple Active Directory domain controllers, Microsoft Systems Management Server (SMS) can be used to install Password Change Notification Service.msi remotely. For more information, see the Microsoft Web Site. (https://www.microsoft.com/)

Configure the service principal name

After installing PCNS, you will need to configure the service principal name (SPN) for the server running FIM.

Important

The SPN cannot be set on a local account, and therefore the FIM Synchronization Service service account must configured as a domain account. To change the FIM Synchronization Service service account from a local account to a domain account, create the domain account, re-run FIM setup in repair mode and specify the new domain account.

The SPN is configured by using setspn.exe, a utility included with the Windows 2000 Resource Kit Tools, and Windows Server 2003 Support Tools on the Windows Server 2003 operating system disk. Setspn.exe can be downloaded from the Microsoft Web Site.(https://www.microsoft.com/).

To set the SPN for the server running FIM, type the following command at the command prompt:

setspn.exe -ASPN prefix/FIMservername Domain\FIMAccount

where:

  • SPN prefix is a user-defined name to indicate that this is a target server for the PCNS, for example "PCNSCLNT"

  • FIMservername is the fully qualified domain name of the server running FIM, for example fab-dev-01.usergroup.fabrikam.com

    Important

    FIMservername must be a fully qualified domain name for authentication to be successful.

  • Domain\FIMAccount is the Domain\User Name of the FIM Synchronization Service service account. Although an SPN is usually assigned to a computer account, the SPN is assigned to the FIM Synchronization Service service account for password synchronization.

    Note

    The SPN must be unique and cannot appear on any other account or the Kerberos authentication fails and passwords do not flow. If you receive an error indicating that the SPN was found on more than one account, you can determine which accounts the SPN is on by using ldifde.exe: ldifde -faccounts.txt-r "(servicePrincipalName=SPNprefix)" -l "cn,dn,servicePrincipalName" where: accounts.txt is the name and path of the user-specified output file SPNprefix is the SPN prefix specified when you ran setspn.exe.

Configuring the management agent

  • For each management agent that is a target for password synchronization:

  • Enable password management for that management agent.

  • For file-based and database management agents, specify the password extension name.

  • Determine whether to stop with an error or continue the synchronization if a non-secure connection is detected for the target data source.

  • Configure the time FIM waits before reattempting a failed password operation.

  • Set the maximum number of times that a failed password operation is retried.

For more information about configuring management agents for password synchronization, see Configure Password Management and Specify Rules Extensions.

Configuring Forefront Identity Manager

Configure FIM to receive password events from Active Directory

  • Select which Active Directory partitions to enable as password synchronization sources.

  • Select which management agents are targets for password synchronization events from the Active Directory source, and the maximum number of password changes to process.

    For more information, see Configure Directory Partitions.

Enable password synchronization on FIM

  • For security reasons, password synchronization is not enabled by default. When you enable password synchronization, the RPC server on the server running FIM is started. For more information, see Enable Password Synchronization.

Important

If the PCNS is already configured on the Active Directory domain before password synchronization is enabled, password change events could be in the PCNS queue, and can be lost if FIM is not fully configured. Therefore, ensure that all target management agents and sources are configured before enabling password synchronization on FIM.

Diagnostics and maintenance

  • Whenever a password change operation completes, the history is saved in the FIM Synchronization Service database in SQL Server. Because a large number of password change operations can increase the size of the database, it is recommended that you save and clear the password change history on a regular basis to limit performance issues on the server running SQL Server. For information about clearing the password change history, see the FIM Developer Reference.

  • Both FIM and the PCNS use the Application log to record activity and failure events. For learning about password synchronization, it is recommended that you set the logging level to high and monitor the Application log closely during the initial configuration and rollout of password synchronization.

    For FIM, there are four logging levels that are controlled by adding the FeaturePwdSyncLogLevel (REG_DWORD) entry to the following registry subkey:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\FIMSynchronizationServices\Logging

    • 0 = Minimal Logging

    • 1 = Normal logging (default)

    • 2 = High logging

    • 3 = Verbose logging

    For PCNS, there are four logging levels that are controlled by adding the EventLogLevel (REG_DWORD) entry to the following registry subkey:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\PCNSSVC\Parameters

    • 0 = Minimal Logging

    • 1 = Normal logging (default)

    • 2 = High logging

    • 3 = Verbose logging
