SLES server won't log login information by default

SUSE Linux Enterprise Server 11

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


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' 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.


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