To answer that question we would need to know what version of KixTart 3.x or 4.x you are using. Please review this thread: http://www.kixtart.org/ubbthreads/showflat.php?Cat=&Board=UBB2&Number=62086

If you are using the 4.x KiXtart, then INGROUP processes the group memberships are attached to the user's security token by the AD global catalog server.
