Authentication and sessions

[musiclover77]

I too have the same problem,
I want to login from the outside of vBulletin.
Some one told me that this will work :

session_start();
$session["userid"]=$_SESSION['mid'];
	$newsession =& new vB_Session($vbulletin, '', $vbulletin->userinfo['userid'], '', $vbulletin->session->vars['styleid']);
	$newsession->set('userid', $_SESSION['mid']);
	$newsession->set('loggedin', 1);
	$newsession->set('bypass', 1);
	//$newsession->set_session_visibility(($vbulletin->superglobal_size['_COOKIE'] > 0));
	$vbulletin->session =& $newsession;
	//($hook = vBulletinHook::fetch_hook('login_process')) ? eval($hook) : false;

But its not working
