title: Give not logged in users a role as 'Guest'
body: <p>I am new to the framework cakephp and I am using the Authentication component as well as the ACL. I have followed this tutorial: <a href="http://book.cakephp.org/2.0/en/tutorials-and-examples/simple-acl-controlled-application/simple-acl-controlled-application.html" rel="nofollow">http://book.cakephp.org/2.0/en/tutorials-and-examples/simple-acl-controlled-application/simple-acl-controlled-application.html</a> to get me started.</p>
  
  <p>How do I give a not logged in User a role (group) ACL such as 'Guest'?</p>
  
  <p>Should I even consider giving a not logged in user such a role (group) ACL? I mean would it bring any disadvantages? </p>
