title: Picketlink single logout from IDP
body: <p>I am using Picketlink to achieve SSO between two applications (one is IDP and one is service provider). I am dealing with problem about logout for two days. Applications are running on Jboss 7.1.1.
  So, the scenario is as follows:</p>
  
  <ol>
  <li><p>I login to my IDP, index page of IDP app is shown. Ok, as expected.</p></li>
  <li><p>I try to access some page in service provider application. Ok, login
  page didn't appear (because I am logged in to IDP), and requested
  page is shown. As expected.</p></li>
  <li><p>Now I hit logout button in my IDP app, session is invalidated and I
  am logged out from IDP. As expected.</p></li>
  <li>Now if I try to access some page in service provider app, this page
  is shown without login screen. This behaviour is unexpected for me
  because I want to be redirected again to IDP login page.</li>
  </ol>
  
  <p>Picketlink documentation is very obscure and I can't find if that behaviour is expected. Does anyone know if this is Picketlink default behaviour or I have configuration problems.</p>
  
  <p>Thanks!</p>
