[Samba] See if authenticated user is in group XYZ

[Jeremiah Martell]

I have winbindd running.
I run wbinfo -a userXYZ%pass and it succeeds

Now I want to know if userXYZ is in group "monkeys", but I dont want
to have to have to map anything. Is this possible? Is there a way to
just say "give me the windows group names that userXYZ is in?" or "is
userXYZ in windows group name 'monkeys'?"

  Thanks!
