title: Liferay - autologin hook/portlet doesn't logout the current user
body: <p>It seems Liferay's autologin hook doesn't logout the current user. So I tried to do it programmatically with the following method call:</p>
  
  <pre><code>request.getSession().invalidate();
  </code></pre>
  
  <p>but with no success.Does anyone had the same issues with the auto-login hook ?</p>
