The Microsoft Directory Synchronization Services tool (MSDSS) may not migrate group membership when synchronizations are run. MSDSS migrates only members of "Security Equal To Me" by default.
This issue occurs because "Security Equal To Me" is the closest equivalent to how groups are used by Active Directory.
