3.8 quality score

We run a couple of automated
scans to help you access a
module's quality. Each module is
given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

Please note, the information below
is for guidance only and neither of
these methods should be considered
an endorsement by Puppet.

erwbgy/pamldap — version 0.1.1 Jan 31st 2013


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

Currently only tested on Redhat-like systems.


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://', 'ldap://' ]

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

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


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
$ 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


This is based on detailed documentation and setup by my colleague Neil McBennett. He did all the hard work, I just puppetised it.
