pam_limits.so [conf= /path/to/limits.conf] [debug] [set_all] [utmp_early] [noaudit]

Some broken applications actually allocate a utmp entry for the user before the user is admitted to the system. If some of the services you are configuring PAM for do this, you can selectively use this module argument to compensate for this behavior and at the same time maintain system-wide consistency with a single limits.conf file.noaudit
Do not report exceeded maximum logins count to the audit subsystem.
