OpenLDAP

Overview

The openldap module allows you to easily manage OpenLDAP with Puppet. By default it will use OLC (cn=config).

Features supported

Object	olc (slapd.d)
global_conf	Y
database	Y
module	Y
overlay	Y
access	Y
index	Y
schema	Y

Usage

Configuring the client

class { 'openldap::client': }

For a more customized configuration:

class { 'openldap::client':
  base       => 'dc=example,dc=com',
  uri        => ['ldap://ldap.example.com', 'ldap://ldap-master.example.com:666'],
  tls_cacert => '/etc/ssl/certs/ca-certificates.crt',
}

Configuring the server

class { 'openldap::server': }
openldap::server::database { 'dc=foo,dc=example.com':
  ensure => present,
}

For a more customized configuration:

class { 'openldap::server':
  ldaps_ifs => ['/'],
  ssl_cert  => '/etc/ldap/ssl/slapd.pem',
  ssl_key   => '/etc/ldap/ssl/slapd.key',
}

If you need multiple databases:

class { 'openldap::server':
  databases => {
    'dc=foo,dc=example,dc=com' => {
      directory => '/var/lib/ldap/foo',
    },
    'dc=bar,dc=example,dc=com' => {
      directory => '/var/lib/ldap/bar',
    },
  },
}

Configuring a global parameter:

openldap::server::globalconf { 'security':
  ensure => present,
  value  => 'tls=128',
}

Configuring multiple olc serverIDs for multiple master or mirror mode

openldap::server::globalconf { 'ServerID':
  ensure  => present,
  value   => { 'ServerID' => [ '1 ldap://master1.example.com', '2 ldap://master2.example.com' ] }
}

Configuring security for global

openldap::server::globalconf { 'Security':
  ensure  => present,
	value   => { 'Security' => [ 'simple_bind=128', 'ssf=128', 'tls=0' ] }

Configuring a database

openldap::server::database { 'dc=example,dc=com':
  directory => '/var/lib/ldap',
  rootdn    => 'cn=admin,dc=example,dc=com',
  rootpw    => 'secret',
}

rootpw will be automatically converted to a SSHA hash with random salt.

Support SHA-2 password

openldap::server::database { 'dc=example,dc=com':
  directory => '/var/lib/ldap',
  rootdn    => 'cn=admin,dc=example,dc=com',
  rootpw    => '{SHA384}QZdaK3FnibbilSPbthnf3cO8lBWsRyM9i1MZTUFP21RdBSLSNFgYc2eFFzJG/amX',
}

Configuring modules

openldap::server::module { 'memberof':
  ensure => present,
}

Configuring overlays

openldap::server::overlay { 'memberof on dc=example,dc=com':
  ensure => present,
}

Configuring ACPs/ACLs

Documentation about olcAcces state the following spec:

5.2.5.2. olcAccess: to <what> [ by <who> [<accesslevel>] [<control>] ]+

Define priority and suffix in the title:

openldap::server::access { '0 on dc=example,dc=com':
  what     => 'attrs=userPassword,shadowLastChange',
  access   => [
    'by dn="cn=admin,dc=example,dc=com" write',
    'by anonymous auth',
    'by self write',
    'by * none',
  ],
}

from the openldap documentation

The frontend is a special database that is used to hold database-level options that should be applied to all the other databases. Subsequent database definitions may also override some frontend settings.

So use the suffix 'cn=frontend' for this special database

openldap::server::access { '0 on cn=frontend' :
  what   => '*',
  access => [
    'by dn.exact=gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth manage',
    'by * break',
  ],
}

Note:

For purging unmanaged entries, rely on the resources resource:

resources { 'openldap_access':
  purge => true,
}

openldap::server::access { '0 on dc=example,dc=com':
  what   => ...,
  access => [...],
}
openldap::server::access { '1 on dc=example,dc=com':
  what   => ...,
  access => [...],
}

Call your acl from a hash:

The class openldap::server::access_wrapper was designed to simplify creating ACL. Each ACL is distinct hash in order to avoid collisions when multiple identical what are present (to * in this example).

$example_acl = [
  {
    'to *' => [
      'by dn.exact=gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth manage',
      'by dn.exact=cn=admin,dc=example,dc=com write',
      'by dn.exact=cn=replicator,dc=example,dc=com read',
      'by * break',
    ],
  },
  {
    'to attrs=userPassword,shadowLastChange' => [
      'by dn="cn=admin,dc=example,dc=com" write',
      'by self write',
      'by anonymous auth',
    ],
  },
  {
    'to *' => [
      'by self read',
    ],
  },
]


openldap::server::access_wrapper { 'dc=example,dc=com' :
  acl => $example_acl,
}

Configuring Schemas

openldap::server::schema { 'samba':
  ensure  => present,
  path    => '/etc/ldap/schema/samba.schema',
  require => Openldap::Server::Schema["inetorgperson"],
}

openldap::server::schema { 'nis':
  ensure  => present,
  path    => '/etc/ldap/schema/nis.ldif',
  require => Openldap::Server::Schema["inetorgperson"],
}

Configuring Rewrite-overlay

openldap::server::database { 'relay':
  ensure  => present,
  backend => 'relay',
  suffix  => 'o=example',
  relay   => 'dc=example,dc=com',
}->

openldap::server::overlay { "rwm on relay":
  ensure  => present,
  suffix  => 'cn=config',
  overlay => 'rwm',
  options => {
    'olcRwmRewrite' => [
      'rwm-rewriteEngine "on"',
      'rwm-suffixmassage , "dc=example,dc=com"]',
  },
}

Configuring Dbindex

# Configuration suffix
Openldap::Server::Dbindex {
  suffix => 'dc=example,dc=com',
}

# The module only sets "objectClass eq" by default
openldap::server::dbindex {
  'cn':
    attribute => 'cn',
    indices   => 'eq,pres,sub';
  'uid':
    attribute => 'uid',
    indices   => 'eq,pres,sub';
  'uidNumber':
    attribute => 'uidNumber',
    indices   => 'eq,pres';
  'gidNumber':
    attribute => 'gidNumber',
    indices   => 'eq,pres';
  'member':
    attribute => 'member',
    indices   => 'eq,pres';
  'memberUid':
    attribute => 'memberUid',
    indices   => 'eq,pres';
}
