thank you kindly for your quick reply. i have been investigating the
ldapsam:trusted = yes option. initially i was unsuccessful until i
added the sambaGroupMapping objectclass to the cn=user,ou=Group...
entry. is this the right place to do this? also, i enter the group
type as "2", i think (for a domain group), but in the sambaSID in the
group mapping, do i copy the individual user's sambaSID or the
sambaPrimaryGroupSID from their entry in uid=user,ou=People... ?
it works with ldapsam:trusted = yes if i do either, but i'm guessing
that i should duplicate the user's sambaSID from their
uid=user,ou=People entry into their cn=user,ou=Group entry. is this
again, thank you kindly. -a
