Subject: Helper functions to enable domain groups to be added to builtin
 groups at domain join time

Added two new helper functions which wrap the raw pdb alias functions so they
can be more conveniently called while adding domain groups to builtin groups.
(This used to be commit 668ef314559df40f1b8aa0991539adcd8d35ffe3)
