I'm not sure how to diagnose PAM. I renamed /etc/pam.d/sudo to
/etc/pam.d/sudo-disabled and after reboot the result is the same.

Yes, specifically RHEL 5.10 with no updates:
[user at localhost ~]$ cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 5.10 (Tikanga)

I'm running it in Virtual Box just to answer one question at SO –
