That was, what I expected, so I already configured it like that:
$conf['group']['params']['search']['objectclass'] = array('group');
$conf['group']['params']['search']['filter_type'] = 'objectclass';

But these settings seem not to be respected in  
Horde/Groups/Ldap.php:listAll(), when called by admin/groups.php.
An inserted print_r($this->_filter) at the beginning of listAll() gives:
Horde_Ldap_Filter Object ( [_filters:protected] => Array ( )  
[_operator:protected] => [_filter:protected] =>  
(objectclass=posixGroup) )

So do we need to setup the correct filter first?

Sorry, I meant in admin/groups.php.
