I am having a Windows DC, but that's not really the point.  What I'm
looking for is something which should work also for users which just
have a Windows client OS and a Linux machine sitting under their desk,
whihc no domain setup at all.  The idea was that there's an automatic
mapping from the user and primary group SIDs in the Windows user token
of the authenticating user to a uid/gid pair on the Samba machine, using
the information in the usermap file.  However, since Volker mentioned
that there are no SIDs transferred from the Windows client machine to
the server at authentication time, there's not much chance that this
would work as I had hoped for.
