Are you running winbindd?  You'll need this before the your non-UNIX
users can own files.  Once it's working, you should be able to do
something like "chown DOMAIN\\user text.txt".

Group mapping (in my experience) doesn't work that well with winbind -
but winbind handles groups as well as users, so that shouldn't be a
problem.  One thing to bear in mind is that any new files created will
be owned by the user's *primary* group (which is probably 'Domain
Users') but you can make new files belong to the same group as the
folder by running "chmod g+s ." - then any new files created in that
folder will belong to the same group as the folder itself.

Cheers,
Adam.
