** Glen Eustace <G.Eustace@massey.ac.nz>
**    user name caching for b-i-g password files
** Paul Emerson <paul@sdgsun.uucp>
**    cleaning up Interactive 386/ix handling, fixing the lp
**    interface, and generally tidying up the sources
** Keith Ericson <keithe@sail.labs.tek.com>
**    more 386/ix fixes
** Jeff Stearns <jeff@tc.fluke.com>
**    setuid/setgid for lpr
** Peter Van Campen <petervc@sci.kun.nl>
**    fixing setuid/gid stuff, syslog
** Ted Nolan <ted@usasoc.soc.mil>
**    /usr/adm/wtmp, other security suggestions

** Thanks to everyone who has contributed.

** in pcnfsd_misc.c for more details.

** Note: For some reason that I haven't yet figured out, getusershell()
** only seems to work when RPC_SVC_FG is defined (for debugging). It doesn't
