Unmaintained

I no longer use Puppet actively and this software has not been maintained for some time.

puppet-pamldap

Configure a system to use LDAP for user authentication, authorisation and related name resolution.

Currently only tested on Redhat-like systems.

Usage

Include the pamldap module in your puppet configuration:

include pamldap

and add required hiera configuration - for example:

pamldap::base_dn: 'dc=example,dc=com'
pamldap::uris: [ 'ldap://10.7.96.13', 'ldap://10.7.96.14' ]

It can also be used as a parameterised class - for example:

class { 'pamldap':
  base_dn => 'dc=example,dc=com',
  uris    => [ 'ldap://10.7.96.13', 'ldap://10.7.96.14' ],
}

Parameters

base_dn: LDAP base distinguished name used in user and group entries

uris: LDAP server connection details - a list of URIs in the format ldap:://[hostname]

Show user and group info from LDAP

Create userinfo and groupinfo aliases in ~/.bashrc:

$ vim ~/.bashrc
alias userinfo='perl -le "print join(qw(:),getpwnam(\$_)) foreach @ARGV"'
alias groupinfo='perl -le "print join(qw(:),getgrnam(\$_)) foreach @ARGV"'

Then you can query user and group information from LDAP that you would normally see in /etc/passwd and /etc/group:

$ groupinfo users
users:x:100:
$ userinfo kburdis fbloggs
kburdis:x:500:100:::Keith Burdis:/home/kburdis:/bin/bash
fbloggs:x:501:100:::Fred Bloggs:/home/kburdis:/bin/bash

When run as root you will see information from LDAP that would normally be in /etc/shadow:

# userinfo kburdis fbloggs
kburdis:$6$oniRviiF...:500:100:::Keith Burdis:/home/kburdis:/bin/bash
fbloggs:$7$OghzqIlp...:501:100:::Fred Bloggs:/home/fbloggs:/bin/bash
# groupinfo sysadmins users
sysadmins:x:514:kburdis
users:x:100:
