validate() returns false for Wordpress and MyOpenid

[GoogleCodeExporter]

Google login works but using the Wordpress OpenID plugin or MyOpenid the 
validate() function fails.

<?php
require 'openid.php';

$openid = new LightOpenID('domain.netaction.de');

if(isset($_POST['openid_identifier'])) {
  $openid->identity = $_POST['openid_identifier'];
  header('Location: ' . $openid->authUrl());
}

if ($openid->validate()) echo 'Accepted OpenID: '.$openid->identity;
?>
<form action="" method="post">
OpenID: <input type="text" name="openid_identifier" /> <input type="submit" />
</form>

After disabling both Open_Basedir and Safe_Mode everything works.
