RH 7.2. pam-0.75-14. While trying to get LDAP authentication to work, I have somehow disabled access to root by all means. I can't ssh as root, or su, or login. Nothing. Normal users are authenticated without problems. Fearing that connectivity with the LDAP server could be causing problems, I have unconfigured all mention of LDAP in the machine (using authconfig). I even re-installed the pam RPM to make sure all the pam.d conf files are OEM. What else can I look for? -- Drew /var/log/secure: Nov 28 11:53:08 morris pam_stack[18865]: called for "PAM_AUTHENTICATE" Nov 28 11:53:08 morris pam_stack[18865]: called from "su" Nov 28 11:53:08
