RE: 1.3.12-4: editing /etc/passwd causes ssh to fail

["Harig, Mark A." <maharig at idirect dot net>]

solution -- back out my changes.  I haven't had time to investigate what
is causing the problem but it starting occurring in one of the recent
releases of ssh in which privilege separation was added.
