##Limitations This module has been built on and tested against Puppet 3.2.4

The module has been tested on:

  • RedHat Enterprise Linux 6.4 (32/64-bit)
  • RedHat Enterprise Linux 7.0 (64-bit)
  • CentOS 5.9 (32/64-bit)
  • CentOS 6.4 (32/64-bit)

  • Ubuntu 14.04 (32/64-bit)

If you test the module on other Linux distributions (or different versions of the above), please provide feedback as able on successes or failures. We will work to add support for other operating systems and Linux distributions soon.

Caution: The use of this module will edit OpenSSH and/or PAM configuration files depending on the usage defined. These modifications have only been tested against default distribution configurations and could impact your settings. Be sure to test this module against non-production systems before attempting to deploy it across your critical infrastucture.
