Module description

This module manages PAM including accesslogin and limits.conf with functionality to create limits fragments for use in other modules. There are examples for using this with VAS/QAS.

Setup

What pam affects

Manages the packages and files regarding PAM. These vary by platform though generally include things such as the following.

  • /etc/pam.conf
  • /etc/pam.d
  • /etc/security/access.conf
  • /etc/security/limits.conf
  • /etc/security/limits.d

Setup requirements

This module requires stdlib. When deployed by default it will require nsswitch. See below for more information.

Optional

nsswitch

By default this module will include the nsswitch class with the settings pam::manage_nsswitch. This module is meant to be used with the Approved nsswitch module.

SSSD

This module has been deployed in production along with sgnl05/sssd. Please see examples/hiera/sssd/RedHat-6.yaml file for an example with the additional SSSD entries added via hiera.

Beginning with pam

Include the main pam class.

Specifying the allowed users

Example using an array

As an array where the origin for each is 'ALL'.

pam::allowed_users:
  - root
  - ops
  - devs

This would create /etc/security/access.conf with the following content.

# This file is being maintained by Puppet.
# DO NOT EDIT
#

# allow only the groups listed
+:root:ALL
+:ops:ALL
+:devs:ALL

# default deny
-:ALL:ALL
Example using a hash

As a hash where the user/group can optionally specify the origin.

pam::allowed_users:
  'username':
  'username1':
    - 'cron'
    - 'tty0'
  'username2': 'tty1'

This would create /etc/security/access.conf with the following content.

# This file is being maintained by Puppet.
# DO NOT EDIT
#

#allow only the groups listed
+:username:ALL
+:username1:cron tty0
+:username2:tty1

# default deny
-:ALL:ALL

Setting limits

Example:
pam::limits_fragments:
  custom:
    list:
      - '* soft nofile 2048'
      - '* hard nofile 8192'
      - '* soft as 3145728'
      - '* hard as 4194304'
      - '* hard maxlogins 300'
      - '* soft cpu 720'
      - '* hard cpu 1440'

This would create /etc/security/limits.d/custom.conf with content

# This file is being maintained by Puppet.
# DO NOT EDIT
* soft nofile 2048
* hard nofile 8192
* soft as 3145728
* hard as 4194304
* hard maxlogins 300
* soft cpu 720
* hard cpu 1440

Specifying the content of a service

Manage PAM file for specific service.

Example:

You can specify a hash to manage the services in Hiera

pam::services:
  'sudo':
    content : 'auth     required       pam_unix2.so'

Usage

Minimal and normal usage.

include pam
