Build Status

limits-formula

SaltStack formula for setting user limits in PAM module

Description

The pam_limits.so module applies ulimit limits, nice priority and number of simultaneous login sessions limit to user login sessions. This description of the configuration file syntax applies to the /etc/security/limits.conf file and *.conf files in the /etc/security/limits.d directory.

Tests

The Travis CI tests run the state on a Ubuntu server. By running the state it checks that there is no syntax errors and that it works for Ubuntu. Other operating systems are NOT tested therefore have a risk of not working on them. ServerSpec is used to verify that the state installed the proper packages and created limits.conf with the proper owner, group, mode and settings.
