I wonder if IBM overlooked a severe bug in AIX 2.2.1. When I tried to
use SCCS one of these days, the machine told me that my user ID could
not be found in the passwd file and that I should contact my Administrator.
After contacting myself :-) (after all, I *AM* the administrator), I
tried the same thing under the root account, with the result that this
time I got "Memory fault - core dumped". That intrigued me enough to
make some further tests. It seems that the SCCS commands (admin in
particular) try to access /etc/security/passwd, which of course fails
for "normal" users. Once i open /etc/security for the public, they too
get the "Memory fault". (Whew. What a relief :-)

That still doesn't solve the problem, though. It just gives you the idea
that someone at IBM didn't test these things before they were shipped.
But then again I might be wrong. I looked all over the manual and found
nothing unusual. So here's my question:

Does SCCS under AIX 2.2.1 need any kind of special setup? Or have I
stumbled onto a bug? If so, is this a known bug of 2.2.1? I would appreciate
any hints ...

I haven't seen this behavior.  We have a large SCCS archive that's
accessed several hundred times a week, always by ordinary users,
some from the source server (2.2.1) system and some by NFS from other
2.2.1, 2.2, and non-IBM systems.

This sounds like a file permission problem.  I have no idea which file(s),
but probably not the SCCS utilities.  They have ordinary permissions
on our systems (user bin, group bin, a=rx).

At AWD all of the AIX sources are kept under SCCS.  This stuff is
accessed thousands of times a day and I've never heard of any trouble,
other than an RT runs slow if you put more than 100 people on it ;-)

Your s-files may be corrupt.  You might want to examine your data files
by hand and see if the contents are correct.

The problem is that I am unable to create an SCCS archive in the first
place. If I try to create one using

                         admin -itest.c s.test.c

I get the memory fault. I haven't tried archives from other systems yet,
but I will do that RSN.
