!"it depends". What do you mean by "login"? Run a shell, and lots of
!different commands? That would probably involve inserting something into
!libc. If you instead want to just run a limited set of programs (eg
!imapd, popd, ftpd, ...) you can instead just hack those applications to
!support what you want. We do this on our primary mailserver - the passwd
!file has only the system maintenance accounts in it, nothing else.

I was hoping run a shell and all that implies, but without other
changes, it would apparently take another module that could create an
entry in /etc/passwd or make all users without one (who passed the
other authentication) fit into some kind of preexisting "guest"
