I am running a SLES10 server under z/VM. This server also runs NIS

closed." For those that do complete a login, if they try to su to
any of
the available root user names, it does not change the userid to
root. If
they give the wrong password for the root username, the system
correctly
detects it and denies the switch. There are no error messages to
indicate why this is happening. The contents of the /etc/passwd file
are
similar to /etc/passwd files on other servers in the shop, since they
are basically clones. The server has been rebooted with no effect on
this issue.
Any thoughts on where to go from here?
Turn on debug in your PAM security stacks and see if you get useful
diagnostic output.
