Nice work, Hartmut.
I fully agree with Corinna's approach. Let's keep it simple.

I have one concern: does subauthentication require access
to the PDC for domain users?
Using NtCreateToken doesn't *when* setgroups has been called.

I would prefer keeping it that way, thus possibly skipping the
call to subauth when setgroups has been called (ftpd, telnetd, 
sshd do not call setgroups, AFAIK). It is also unlikely that
the token created by subauth would match the groups specified
by setgroups.
