Is this a group?  Have you tried with a specific user?  Did you try
removing the quotes?  This works for me:

  valid users = @DOMAIN\user

But I haven't tried it with an AD group.  If you can't get it to work
with an individual user then it's probably a problem with your
configuration.

Cheers,
Adam.
