Here's something I ran though the other day on Active Directory Groups. Let's say you have the following groups in Active Directory:
By default, if you synchronize the AD group "PW Users" using the User Synchronization Service, you will get the following group in ProjectWise:
Add the following DWORD Value to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PWAutSrv: "CreateEnumeratedSubGroups" = 1
Now when you synchronize the AD group "PW Users" using the User Synchronization Service, you will get the following ProjectWise groups:
In summary, if HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PWAutSrv "CreateEnumeratedSubGroups" = 0 or is not defined, then no sub groups will be synchronized. "CreateEnumeratedSubGroups" = 1, then sub groups will be synchronized.
