Non-root users cannot do things like su, ps, crontab -l

I'm having a strange problem with a Tru64 Unix V5.1 system. We have zillions
of these systems and I've never seen anything like this. I'm suspicious that
"someone did something", but exactly what I haven't determined.

The problem is that non-root users cannot do various things. This includes
things like "ps aux" (it just returns the top header line containing column
descriptions), "crontab -l" (says it can't open their crontab file) or "su"
(just goes back to the shell prompt -- no errors. yes, the login account has
been added to the system group).

One weird thing I noticed was that the secure shell was running (sshd2). I
killed it and removed it. Tried rebooting the system to no avail. I've also
uninstalled C2 security. I've also rebuild my /etc/sia/matrix.conf file
using "BSD". Nothing!

I'm inching toward reinstalling the entire dad-burn O/S from scratch, but
would like to get to the bottom of this. Anyone have any clues?

Much thanks,

Chris
