Puppet OpenLDAP Module

Introduction

Puppet module to manage client and server configuration for OpenLdap.

Usage

Ldap client

Ldap client configuration at its simplest:

class { 'ldap::client':
	uri  => 'ldap://ldapserver00 ldap://ldapserver01',
	base => 'dc=foo,dc=bar'
}

Enable TLS/SSL:

Note that ssl_cert should be the CA's certificate file, and it should be located under puppet:///files/ldap/.

class { 'ldap::client':
	uri      => 'ldap://ldapserver00 ldap://ldapserver01',
	base     => 'dc=foo,dc=bar',
	ssl      => true,
	ssl_cert => 'ldapserver.pem'
}

Enable nsswitch and pam configuration (requires both modules):

class { 'ldap::client':
  uri      => 'ldap://ldapserver00 ldap://ldapserver01',
  base     => 'dc=foo,dc=bar',
  ssl      => true
  ssl_cert => 'ldapserver.pem',

  nsswitch   => true,
  nss_passwd => 'ou=users',
  nss_shadow => 'ou=users',
  nss_group  => 'ou=groups',

  pam        => true,
}

OpenLdap Server

Master server

OpenLdap server as simple as it is:

class { 'ldap::server::master':
  suffix      => 'dc=foo,dc=bar',
  rootpw      => '{SHA}iEPX+SQWIR3p67lj/0zigSWTKHg=',
}

Configure an OpenLdap master with syncrepl enabled:

class { 'ldap::server::master':
  suffix      => 'dc=foo,dc=bar',
  rootpw      => '{SHA}iEPX+SQWIR3p67lj/0zigSWTKHg=',
  syncprov    => true,
  sync_binddn => 'cn=sync,dc=foo,dc=bar',
  modules_inc => [ 'syncprov' ],
  schema_inc  => [ 'gosa/samba3', 'gosa/gosystem' ],
  index_inc   => [
    'index memberUid            eq',
    'index mail                 eq',
    'index givenName            eq,subinitial',
    ],
}

With TLS/SSL enabled:

class { 'ldap::server::master':
  suffix      => 'dc=foo,dc=bar',
  rootpw      => '{SHA}iEPX+SQWIR3p67lj/0zigSWTKHg=',
  ssl         => true,
  ssl_ca      => 'ca.pem',
  ssl_cert    => 'master-ldap.pem',
  ssl_key     => 'master-ldap.key',
}

NOTE: SSL certificates should reside in you puppet master file repository 'puppet:///files/ldap/'

Slave server

Configure an OpenLdap slave:

class { 'ldap::server::slave':
  suffix        => 'dc=foo,dc=bar',
  rootpw        => '{SHA}iEPX+SQWIR3p67lj/0zigSWTKHg=',
  sync_rid      => '1234',
  sync_provider => 'ldap://ldapmaster'
  sync_updatedn => 'cn=admin,dc=foo,dc=bar',
  sync_binddn   => 'cn=sync,dc=foo,dc=bar',
  sync_bindpw   => 'super_secret',
  schema_inc    => [ 'gosa/samba3', 'gosa/gosystem' ],
  index_inc     => [
    'index memberUid            eq',
    'index mail                 eq',
    'index givenName            eq,subinitial',
    ],
}

Notes

Ldap client / server configuration tested on:

• Debian: 5 / 6 / 7
• Redhat: 5.x / 6.x
• CentOS: 5.x / 6.x
• OpenSuSe: 12.x
• SLES: 11.x

Should also work on (I'd appreciate reports on this distros and versions):

• Ubuntu
• Fedora
• Scientific Linux 6

Requirements

• If nsswitch is enabled (nsswitch => true) you'll need puppet-nsswitch
• If pam is enabled (pam => true) you'll need puppet-pam
• If enable_motd is enabled (enable_motd => true) you'll need puppet-motd

TODO

• ldap::server::master and ldap::server::slave do not copy the schemas specified by index_inc. It just adds an include to slapd
• Need support for extending ACLs
