Parameters

class pam

allowed_users

Array or Hash of strings and/or arrays to configure users and origins in access.conf. The default allows the root user/group from origin 'ALL'.

• Default: 'root'

Hiera example for allowed_users

# 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

# 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
