Fixed for real now.

forget this, sorry see http://bugs.horde.org/ticket/6722



But still I do not see any entry in the session table in the db... 
I'll continue to search for the cause :-)

Ok, I found the problem...



in SessionHandler.php there is:



         if ($driver == 'memcached') {

             // Trap for old driver name.

             $driver = 'memcache';

         } elseif (($driver != 'memcache') && !empty($params['memcache'])) {

             $driver = 'memcache';

             unset($params['memcache']);

             $persistent_params = array('persistent_driver' => 
$driver, 'persistent_params' => $params);

             $params = null;

         }



... but the persistent_params are not generated or asked by conf.xml.



I'll file a new bug.

Thanks.

I still get "0", which is correct accourding to the 
"horde_sessionhandler" table. This is strange, should't the sessions 
be written into that table when using the following config:



$conf['sessionhandler']['params']['persistent'] = true;

$conf['sessionhandler']['params']['rowlocking'] = true;

$conf['sessionhandler']['params']['port'] = 3306;

$conf['sessionhandler']['params']['protocol'] = 'tcp';

$conf['sessionhandler']['params']['hostspec'] = 'XXX.XXX.3.24';

$conf['sessionhandler']['params']['username'] = 'horde';

$conf['sessionhandler']['params']['password'] = '****';

$conf['sessionhandler']['params']['database'] = 'horde';

$conf['sessionhandler']['params']['table'] = 'horde_sessionhandler';

$conf['sessionhandler']['type'] = 'mysql';

$conf['sessionhandler']['memcache'] = true;

Fixed.

When using the sql session handler together with memcache session 
caching the session counter just return 0 as numer of sessions.
