The team has recently released the following new content to help you use AD RMS:

• AD RMS Client Requirements – Provides important information about the AD RMS client in a format that you can quickly scan and reference. It includes a section that covers requirements for various versions of the client, and a section on AD RMS service discovery.
• AD RMS and AD FS Considerations – Provides a brief overview of requirements and configuration options for using AD RMS with Active Directory Federation Services (AD FS).
• AD RMS Business-To-Business Requirements for Trusted User Domains – Details the requirements for adding a trusted user domain, which allows the AD RMS root cluster to process requests for client licensor certificates or use licenses from users whose rights account certificates (RACs) were issued by a different AD RMS root cluster.
