We're using Active Directory on Windows 2003 Server.

Yes.

At the moment I am using the version from 29th august.

In our setup the following error occurs:
[07-Sep-2010 13:30:50] PHP Warning:  implode(): Invalid arguments  
passed in /usr/share/php/Horde/Group/Ldap.php on line 498
(one error per Group is written)

var_dump($result); returns NULL -> where is this variable filled?
this is the function:
     public function getGroupParent($dn)
     {
         if (@ldap_explode_dn($dn, 0) === false) {
             throw new Horde_Group_Exception('Invalid group ID passed  
(bad DN syntax)');
         }
         unset($result['count'], $result[0]);

         $parent_dn = implode(',', $result);

         return (Horde_String::lower($parent_dn) ==  
Horde_String::lower($GLOBALS['conf']['group']['params']['basedn']))
             ? DATATREE_ROOT
             : $parent_dn;
     }

When I click on a Group, following error occurs:
[07-Sep-2010 13:33:27] PHP Fatal error:  Call to protected method  
Horde_Group_LdapObject::_fromAttributes() from context  
'Horde_Group_Ldap' in /usr/share/php/Horde/Group/Ldap.php on line 251

Turning _from/_toAttributes to public functions works for me (means  
Groups are "clickable", but still empty).
