That's right.  The reason is that the machine name is treated as a=20
foreign machine.  In theory, this should always generate names
with prefixed machine name, but this is an entirely different
code path in mkpasswd/mkgroup.  I guess this should be fixed.

I wouldn't be unhappy about help...

Uh, yes.  That's what I meant above :}

And how's that supposed to work?  Even if we introduce a way in
/etc/nsswitch.conf to generate usernames differently, it doesn't really
help.  Your config file should be able to work with default settings
and not force the admin to use specific settings in nsswitch.conf.
