This document is intended to help administrators configure various parts of horde to use an existing LDAP directory. Please feel free to fill in any gaps or to clarify any existing information presented here.
In this document, we assume the following, please adjust accordingly for your LDAP directory
The Horde authentication setup should look something like the following:
These are the minimum LDAP directory permissions needed by horde to authenticate against LDAP
access to dn.children="ou=Users,dc=example,dc=com"
attrs=entry,objectClass,uid
by dn="cn=horde,ou=DSA,dc=example,dc=com" read
by self read
by * none
access to dn.children="ou=Users,dc=example,dc=com"
attrs=userPassword
by self write
by anonymous auth
by * none
Storing Horde preferences in the LDAP directory adds a large number of attribute entries to every user DN. If this is something you do not want, you should look into using some other preference backend.
To use LDAP to store Horde preferences, set the preference system to use LDAP as its backend. The field values here are very simular to the Horde configuration.
These are the minimum LDAP directory permissions needed by horde to store user preferences.

----
++ LDAP Based Address Book
+++ Turba Setup
Turba ships with an example LDAP address book, so we will use that here as our base. This example assumes that we are providing an address book containing all of the users who have access to this horde installation.
<code type="php">
$cfgSourses['localldap'] = array(
'title' => _("Shared Directory"),
'type' => 'ldap',
'params' => array(
'server' => 'localhost',
'port' => 389,
'root' => 'ou=Users,dc=example,dc=com',
'bind_dn' => 'cn=horde,ou=Users,dc=example,dc=com',
'bind_password' => '********',
'sizelimit' => 200,
'filter' => '(&(uid=*)(objectClass=posixAccount))',
'dn' => array('cn'),
'objectclass' => array('top',
'person',
'organizationalPerson',
'inetOrgPerson'),
'charset' => 'iso-8859-1',
'checkrequired' => false,
'version' => 3
),
'map' => array(
'__key' => 'dn',
'name' => 'displayName',
'email' => 'mail',
'workPhone' => 'telephonenumber',
'cellPhone' => 'mobile',
'office' => 'roomNumber',
'employeeType' => 'employeeType',
'pgpPublicKey' => 'userCertificate',
'freebusyUrl' => 'calFBURL',
),
'search' => array(
'name',
'email',
'homePhone',
'workPhone',
'cellPhone',
'homeAddress'
),
'public' => true,
'readonly' => true,
'admin' => array(),
'export' => true
);
The amount of information you can store is not by any means limited by what we have configured here. Any number of LDAP fields can be added to the 'map' array.
In order to use the calFBURL field, we have to include the rfc2739 schema in our LDAP configuration file.
include /etc/openldap/schema/rfc2739.schema
These are the minimum LDAP permissions required for the address book we defined above. If you included extra fields, be sure to add them here.
