title: Drupal Shibboleth Logout
body: <p>We have used Shibboleth to authenticate users.  It works great.</p>
  
  <p>The issue is that after going to user/logout (and, I think, actually logging out), the user is  immediately and automatically re-authenticated!</p>
  
  <p>Any solutions come to mind?</p>
  
  <p>Thanks!</p>
