title: phpCAS and CodeIgniter
body: <p>I'm looking for some guidance on how to integrate phpCAS with CodeIgniter.</p>
  
  <p>I've been searching for 2 days and have gotten nowhere.</p>
  
  <p>Does anyone have solid examples of how to do this? I've use authorization libraries for CI in the past but my newest project requires CAS integration.</p>
  
  <p>Thanks for any help you can send my way.</p>
