GRR...  You clearly "do not understand".  No, authentication does NOT=20
come from Hesiod (indeed, if you look up my Hesiod entry you wont even
see a passwd entry!).  Authentication uses Kerberos.  Please -- try to
spoof that!

Yes, you could perform UID spoofing, but you can do that with _ANY_
distributed passwd entry.  The point is that "local UID" means nothing
-- the only thing that matters (at least on the network) is your
kerberos identity.
