Checklist: Deploying AD RMS in an Organization with Users in Multiple Forests
Updated: December 30, 2007
Applies To: Windows Server 2008 R2, Windows Server 2012
Only one Active Directory Rights Management Services (AD RMS) root cluster is permitted per forest. If your organization wants to use rights-protected content in more than one forest, you must have a separate AD RMS root cluster for each forest.
The following steps in this checklist describe the tasks required to deploy AD RMS in an organization with users in multiple forests.
Assign a secure sockets layer (SSL) certificate to the Web site that will be hosting the AD RMS cluster.
Install and configure an AD RMS root cluster in each forest.
If you are not using Exchange Server in each forest, you must extend the Active Directory schema.
Add the AD RMS service account to the access control list of the group expansion pipeline.
