title: Java Security Apache Shiro vs Picketlink
body: <p>I've got an Java EE application running with Apache Shiro to secure and authenticate to the website.</p>
  
  <p>However I want to implement Single Sign on with Picketlink.</p>
  
  <p>Is it possible to implement it "on top" or do I have to disable Shiro and do the whole authentication with Picketlink?</p>
  
  <p>On the web I couldn't find any reference.</p>
