Kohana 3 AUTH loggin issues on specific machines -

i have used kohana on several projects now, included authentication module absolutely 0 issues... until particular client.

at first not log in site on xp machine using ie8. did digging , ended adding config file application/config/session.php

<?php defined('syspath') or die('no direct access allowed.');  /**  * @package session  *  * session driver name.  */ //$config['driver'] = 'native';  /**  * number of page loads before session id regenerated.  * value of 0 disable automatic session id regeneration.  */ //$config['regenerate'] = 0;   // kludge: windows xp sp3 running ie-7 , 8 // http://bit.ly/gpcv67 //$config['validate'] = 'ip_address';      return array(       'cookie' => array(           'name' => 'session_cookie',           'encrypted' => true,           'lifetime' => 43200,       ),       'native' => array(           'name' => 'session_native',           'encrypted' => true,           'lifetime' => 43200,       ),       'database' => array(           'name' => 'session_database',           'group' => 'default',           'table' => 'sessions',       ),   );  ?>

sounds server issue me, @ time of login denied access (session not written?). i'd try memcached or database sessions.
