SLES server won't log login information by default

This document (7002758) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 11
SUSE Linux Enterprise Server 10

Situation

On a SLES11SP1 server (fully patched), successful user logins are not recorded by default, failed login attempts are.

Resolution

There are several ways to fix this, here are a couple of them (this is not an exhaustive list):

1.  Install auditd.

    If you install auditd, by default it will log login information to /var/log/audit/audit.log. 

    NOTE:  If you install auditd, it doesn't enable logging by default, you must use the command 'auditctl -e1' each time you restart the server or auditd, or you can put the '-e1' in the /etc/audit/audit.rules file and it will be persistent across boots.

2.  Configure pam to log authentication information:

    If you edit the /etc/pam.d/common-sessions file, and add 'session required pam_warn.so' at the bottom, this will send authentication information to the /var/log/messages file.

Note: If you are using NetIQ Sentinel, there is a script included (wtmpsetup) in the SLES Collector Pack which will monitor the wtmp and btmp files for logins and generate a suslog message to record the activity.

Cause

By default there is nothing implemented to log or audit authentication information (logins).
