su is OK, but telnet or ssh is not

Bouda16 — Thu, 11 Dec 2008 11:36:05 GMT

Hello guys,
simple problem - I can use su to switch to user, lets say igor, but using telnet or ssh I'm not able to login. It's just kind of "Authentication failure".

Any suggestion?

Check for password expiration. See in syslog/messages files for more information.

Can you post the output of finger , maybe the shell is set to false.

Maybe users are disabled, check for this.

Check some of these files:
Log files:
/var/log/messages, /var/log/audit/*, /var/log/secure.
Configuration files:
/etc/hosts.{allow,deny}
/etc/securetty
/etc/nologin (does it exist?)
/etc/passwd

Have you configured PAM or selinux recently?
