Thread: Active Directory Address Book

RoundCube does support LDAP, change $rcmail_config['address_book_type'] in <RC root>/config/main.inc.php to LDAP. Setup the informaion in the $rcmail_config['ldap_public'] = array();
Here is the notes from the main.inc.php about how to configuration it:

// If you are going to use LDAP for individual address books, you will need to
// set 'user_specific' to true and use the variables to generate the appropriate DNs to access it.
//
// The recommended directory structure for LDAP is to store all the address book entries
// under the users main entry, e.g.:
//
// o=root
// ou=people
// uid=user@domain
// mail=contact@contactdomain
//
// So the base_dn would be uid=%fu,ou=people,o=root
// The bind_dn would be the same as based_dn or some super user login.
/*
* example config for Verisign directory
*
$rcmail_config['ldap_public']['Verisign'] = array(
'name' => 'Verisign.com',
'hosts' => array('directory.verisign.com'),
'port' => 389,
'use_tls' => false,
'user_specific' => false, // If true the base_dn, bind_dn and bind_pass default to the user's IMAP login.
// %fu - The full username provided, assumes the username is an email
// address, uses the username_domain value if not an email address.
// %u - The username prior to the '@'.
// %d - The domain name after the '@'.
'base_dn' => '',
'bind_dn' => '',
'bind_pass' => '',
'writable' => false, // Indicates if we can write to the LDAP directory or not.
// If writable is true then these fields need to be populated:
// LDAP_Object_Classes, required_fields, LDAP_rdn
'LDAP_Object_Classes' => array("top", "inetOrgPerson"), // To create a new contact these are the object classes to specify (or any other classes you wish to use).
'required_fields' => array("cn", "sn", "mail"), // The required fields needed to build a new contact as required by the object classes (can include additional fields not required by the object classes).
'LDAP_rdn' => 'mail', // The RDN field that is used for new entries, this field needs to be one of the search_fields, the base of base_dn is appended to the RDN to insert into the LDAP directory.
'ldap_version' => 3, // using LDAPv3
'search_fields' => array('mail', 'cn'), // fields to search in
'name_field' => 'cn', // this field represents the contact's name
'email_field' => 'mail', // this field represents the contact's e-mail
'surname_field' => 'sn', // this field represents the contact's last name
'firstname_field' => 'gn', // this field represents the contact's first name
'sort' => 'cn', // The field to sort the listing by.
'scope' => 'sub', // search mode: sub|base|list
'filter' => '', // used for basic listing (if not empty) and will be &'d with search queries. example: status=act
'fuzzy_search' => true); // server allows wildcard search

This is how I configured my Active Directory LDAP.
I use a different AD domain to my external domain.
The mail server I am using is hMail with AD authentication.
This example sends the users external login name as an internal login name and password,
ie: user@sample.com, becames user@sample.net.au

MyLDAPService = The name for your LDAP connection
MyServer = the IP address or server name for LDAP connection
internal domain name = sample.net.au

$rcmail_config['ldap_public']['MyLDAPService'] = array(
'name' => 'MyLDAPService',
'hosts' => array('MyServer'),
'port' => 389, // LDAP Port
'use_tls'=> false,
'user_specific' => true,
'base_dn'=> 'DC=sample,DC=net, DC=au',
'bind_dn' => '%u@sample.net.au',
'writable'=> false, // Indicates if we can write to the LDAP directory or not.
'search_fields' => array('mail', 'cn'),
'name_field' => 'cn', // this field represents the contact's name
'firstname_field' => 'givenName', // this field represents the contact's first name
'surname_field' => 'sn', // this field represents the contact's last name
'email_field' => 'mail', // this field represents the contact's e-mail
'scope' => 'sub', // search mode: sub|base|list
'filter' => '(&(mail=*)(!(msExchHideFromAddressLists=TRUE)))' , // all mail, except the exchange hidden
'sort' => 'cn', // The field to sort the listing by.
'fuzzy_search' => TRUE); // server allows wildcard search
