title: SimpleSamlPHP - SimpleSAMLSessionID empty
body: <p>We are currently setting up SAML authentication for the first time, due to a third-partner request. </p>
  
  <p>To integrate some components they have writen, we need to provide some information from <code>$_COOKIE[]</code> after our customer have logged in : <code>SimpleSAMLAuthToken</code> and <code>SimpleSAMLSessionID</code>.</p>
  
  <p>However, the second field seems not to be set by SimpleSamlPHP on our installation :</p>
  
  <pre><code>  $as = new SimpleSAML_Auth_Simple($url_saml);
    $as-&gt;requireAuth();
    print_r($_COOKIE);
  </code></pre>
  
  <p>gives us</p>
  
  <pre><code>Array
  (
      [PHPSESSID] =&gt; r2st6fpu7ju2801cepl3d0****
      [SimpleSAMLAuthToken] =&gt; _e4eceb095eb14e2ab9fc4c53a65d1358b575f3****
  )
  </code></pre>
  
  <p>Would anyone would have an idea of what is going wrong ?</p>
  
  <p>Thanks in advance ! :-)</p>
