Add an AD DS Account Store
Applies To: Windows Server 2008
If user and computer accounts that require access to a resource that is protected by Active Directory Federation Services (AD FS) are stored in Active Directory Domain Services (AD DS), you must add AD DS as an account store on a federation server in the Federation Service that authenticates the accounts.
An Active Directory forest can have only one Active Directory instance. Therefore, you can add only one AD DS account store for the respective Federation Service.
Membership in Administrators, or equivalent, on the local computer is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).
