Bob,
You nailed it. Thanks.
I had to setuid and root.wheel ownership when I originally setup the user, but
"something", which I presume to have been the SuSE online update, unset both.
Since I "knew" that I had made these settings, it didn't occur to this 64 year
old that "perhaps" they had somehow been reverted to their original settings.
After re-resetting them everything seems to be working normally. I got up this
morning expected to have to do a reinstall but fortunately your email saved the
day. Sorry for the bother; and thanks to both you and Paul.
Best Regards,
Phil Welch

Are shadow passwords enabled? Is /bin/su suid-root and able to read
the shadow file? Does the normal password file contain an 'x' and the
actual password reside in /etc/shadow? That would match the stated
behavior.

Makes me thing the suid-root bit is not set on the su command.
Because login does not use su at all.

I don't think that should be needed.
What errors are recorded in the syslog? On my machine that would be
/var/log/auth.log but on yours it is probably /var/log/messages or
some such.
Also, can you verify the following information?
su --version
type su
ls -ld $(type -p su)
If the above is /bin/su then:
rpm -qf $(type -p su)
rpm -V $(rpm -qf $(type -p su))
