For security reasons, this is not allowed.

This is hardwired into pam. The rules don't matter. I'd check that pam was 
compiled with audit support and that audit is enabled in the kernel.

Logging in/out is done in 2 places. First, pam records what it knows. But the 
entry point daemon is also supposed to send USER_LOGIN and USER_LOGOUT 
events.

Complete information is here:
https://github.com/linux-audit/audit-documentation/wiki/SPEC-User-Login-Lifecycle-Events

Gdm, Kdm, and sshd all have been updated to record these events. All that is 
needed is to configure --with-audit during the package build. By now, I would 
expect all distros to do that.

Hi Team,

1)I am using this version of auditctl version 2.4.4 . So does this version has the user login/logout info to log into audit.log ?

2) If u  to want to see the pam.d/login file configuration to check why its not logging the login/logout info then please let me know about this , i will be happy to share that file.or if it needs other pam file to check also please let me know that also.
As i see in my system that [kauditd] is running so it log all login info.
Please help me on this .

This is not the responsibility of auditd. Auditd provides libaudit. 
Applications use that to create log events. It is the reposibility of system 
entry point daemons to log the event. User login events have been supported 
as long as I can remember.

It's not configurable by an end user. Its configured at compile time. You would 
want to look at the build logs for pam and entrypoint daemons such as sshd, 
gdm, kdm, etc.

As I said, the build logs. Listen, do not keep sending emails saying this is 
not working please help. I have no idea what distribution you are using or if 
you have even contacted them. If you are using a distribution, please contact 
them.

You point to syslog and ask why audit is not working. Audit doesn't send to 
syslog, it sends to auditd unless auditd is not running. Is it?

Audit is working for all distributions I know of. If it's not working for 
you, it is incumbent on you to explain what your system is using and how 
you've checked it. Try ldd for example to see if pam is actually linked 
aginst libaudit.
