SULOG for LINUX

How to enable sulog activity in LINUX like /var/adm/sulog in Solaris , AIX.....
I have added
SULOG_FILE /var/log/sulog
in /etc/login.defs ...but it is not working ...

Thanks a lot for help

On modern GNU/Linux distributions, su information is logged via the PAM stack (/etc/pam.d) module pam_unix.so to /var/log/secure.
