WikiMedia API login

Hej!

Jeg prøver at rode lidt med et login til min private wiki. Jeg har kopieret og tilrettet eksemplet fra wikimedia.org
men jeg kan ikke få det til at virke.
Jeg får returneret "SUCEESS", men når jeg prøver at følge et link til min wiki, skal jeg logge ind igen...

Funktioner:

 $settings['wikiroot'] = "http://mit.domæne"; // er selvfølgelig den korrekte adresse i mit eget script.
 $settings['cookiefile'] = "cookies.tmp";
 
 function httpRequest($url, $post="")
 {
     global $settings;
     
     $ch = curl_init();
     //Change the user agent below suitably
     curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.9) Gecko/20071025 Firefox/2.0.0.9');
     curl_setopt($ch, CURLOPT_URL, ($url));
     curl_setopt( $ch, CURLOPT_ENCODING, "UTF-8" );
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
     curl_setopt ($ch, CURLOPT_COOKIEFILE, $settings['cookiefile']);
     curl_setopt ($ch, CURLOPT_COOKIEJAR, $settings['cookiefile']);
     if (!empty($post)) curl_setopt($ch,CURLOPT_POSTFIELDS,$post);
     //UNCOMMENT TO DEBUG TO output.tmp
     //curl_setopt($ch, CURLOPT_VERBOSE, true); // Display communication with server
     //$fp = fopen("output.tmp", "w");
     //curl_setopt($ch, CURLOPT_STDERR, $fp); // Display communication with server
     
     $xml = curl_exec($ch);
     
     if (!$xml)
     {
         throw new Exception("Error getting data from server ($url): " . curl_error($ch));
     }
     
     curl_close($ch);
     
     return $xml;
 }
 
 
 function login ($user, $pass, $token='')
 {
     global $settings;
 
     $url = $settings['wikiroot'] . "/wiki/api.php?action=login&format=xml";
 
     $params = "action=login&lgname=$user&lgpassword=$pass";
     if (!empty($token))
     {
         $params .= "&lgtoken=$token";
     }
 
     $data = httpRequest($url, $params);
     
     if (empty($data))
     {
         throw new Exception("No data received from server. Check that API is enabled.");
     }
 
     $xml = simplexml_load_string($data);
     
     if (!empty($token))
     {
         //Check for successful login
         $expr = "/api/login[@result='Success']";
         $result = $xml->xpath($expr);
 
         if(!count($result))
         {
             throw new Exception("Login failed");
         }
     }
     else
     {
         $expr = "/api/login[@token]";
         $result = $xml->xpath($expr);
 
         if(!count($result))
         {
             throw new Exception("Login token not found in XML");
         }
     }
     
     return $result[0]->attributes()->token;
 }

"Handler":

 if(isset($_POST['wpName']) && isset($_POST['wpPassword']))
 {
     try
     {
         global $settings;
         $token = login($_POST['wpName'], $_POST['wpPassword']);
         login($_POST['wpName'], $_POST['wpPassword'], $token);
         echo("SUCCESS");
     }
     catch (Exception $e)
     {
         die("FAILED: " . $e->getMessage());
     }
 }

 <form action="" method="post">
 <p>Brugernavn <input type="text" name="wpName" id="brugernavn" /></p>
 <p>Adgangskode <input type="password" name="wpPassword" id="adgangskode" /></p>
