Active Directory Rights Management Services Role

Are there any special considerations?

AD RMS relies on Active Directory Domain Services (AD DS) to verify that the user attempting to consume rights-protected content is authorized to do so. When registering the AD RMS service connection point (SCP) during installation, the installing user account must have Write access to the Services container in AD DS.
Finally, all configuration and logging information is stored in the AD RMS Logging Database. In a test environment, you can use the Windows Internal Database, but in a production environment, we recommend using a separate database server.
