title: How to use the information in an LTPA token
body: <p>Consider the following setup:</p>
  
  <ul>
  <li>A webapplication deployed on a Websphere Application Server (6.1 if it matters)</li>
  <li>the app will get accessed through a webseal reverse proxy</li>
  <li>the webseal takes care of the authentication and passes on an LTPA token as sign of valid authentication</li>
  </ul>
  
  <p>If I got it right, the LTPA token contains information like username, roles and so on.</p>
  
  <p>Question: how do I access this information from the LTPA token in my java web application?</p>
