I am running RHEL5 and can't get ssh to work with NIS. I get the error: Permission denied, please try again. when I execute: ssh ilg@localhost The error in /var/log/secure is: sshd[15593]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost= localhost.localdomain user=ilg sshd[15593]: Failed password for ilg from <a href="http://127.0.0.1">127.0.0.1</a> port 1590 ssh2 The /etc/nsswitch.conf has: passwd: compat shadow: compat group: compat and I have the appropriate "+" entries in /etc/passwd, /etc/shadow and /etc/group. I am sure it's not my NIS setup because ypcat and ypmatch all work. I am pretty sure that the problem is that PAM is not using the NIS map files for authentication. The reason I say this is, when I set "UsePAM no" in /etc/ssh/sshd_config - then ssh works and I am able to login. In essence bypassing PAM. or when I copy the login and password entries for ilg from the NIS source files to /etc/passwd and /etc/shadow, then ssh works and I am able to login. In essence bypassing NIS. How do I make PAM use NIS? I am using the default /etc/pam.d files that were installed with the system. Thanks in advance. -Ian
