To turn off Selinux temporarily type setenforce 0 at a root prompt. If turning it off fixes your su - issue then I would relabel your file system all you need to do is type touch /.autorelabel as root and then reboot. You might need to drop to single user mode. If it is a selinux issue I would be curious as to the selinux context errors that are showing up in /var/log/messages <br>

SELinux?<br>
You may have one or more files with a borken context. If that is so,<br>
you can test the theory by turning off enforcement. If it works when<br>
SELinux is not enforcing, then you probably just need to restore the<br>
SELinux context ... maybe of 'su', maybe of /etc/passwd or /etc/shadow<br>
... or maybe just relabel the whole shootin match like some people do<br>
at every reboot. I don't remember the command(s) to restore context<br>
because I turn off SELinux from the get-go.<br>
