RoundCube could list a address book from OpenLdap

 $rcmail_config['ldap_public']['Domain'] = array(
  'name'          => 'Domain',
  'hosts'         => array('localhost'),
  'port'          => 389,
  'base_dn'       => 'dc=domain,dc=com,dc=br',
  'bind_dn'       => 'cn=Manager,dc=domain,dc=com,dc=br',
  'bind_pass'     => 'xxxxxxx',
  '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
  'scope'         => 'sub',   // search mode: sub|base|list
  'filter'        => '',      // will be &'d with search field ex: (status=act)
  'fuzzy_search'  => true);   // server allows wildcard search


But it doesn´t work - Some One know something !?

Thanks
