Cannot choose groups or built in security principal to add to the ManagedBy property
In Windows Server 2003 SP1, Microsoft introduced the ability to add built-in security principal and groups as choices for the ManagedBy property.
DRA does not currently have this ability. An Enhancement Request for this type of functionality is being considered for a future release, however, at this time there has been no decision made to include this feature.
