+pam_limits — PAM module to limit resources
+
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+
+DESCRIPTION
+
+The pam_limits PAM module sets limits on the system resources that can be
+obtained in a user-session. Users of uid=0 are affected by this limits, too.
+
+By default limits are taken from the /etc/security/limits.conf config file.
+Then individual *.conf files from the /etc/security/limits.d/ directory are
+read. The files are parsed one after another in the order of "C" locale. The
+effect of the individual files is the same as if all the files were
+concatenated together in the order of parsing. If a config file is explicitly
+specified with a module option then the files in the above directory are not
+parsed.
+
+The module must not be called by a multithreaded application.
+
+If Linux PAM is compiled with audit support the module will report when it
+denies access based on limit of maximum number of concurrent login sessions.
+
+OPTIONS
+
+conf=/path/to/limits.conf
+
+ Indicate an alternative limits.conf style configuration file to override
+ the default.
+
+debug
+
+ Print debug information.
+
+set_all
+
+ Set the limits for which no value is specified in the configuration file to
+ the one from the process with the PID 1.
+
+utmp_early
+
+ 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.
+
+EXAMPLES
+
+These are some example lines which might be specified in /etc/security/
+limits.conf.
