title: Zend Framework 2 Authentication
body: <p>I have a conceptual question.
  Working on a site for a client. Very simple site. Kind of a mini CMS, almost every section is database driven. My thought is rather than having the main site and then a separate section for editing, I would check for authentication and have the admin user edit the section directly.</p>
  
  <p>My question is, where should that authentication happen? Is it possible/efficient to check from the controller? Or should I check it at the module?</p>
  
  <p>I am using zfcUser (if that makes any difference)</p>
  
  <p>Thanks</p>
