title: symfony2 rest api conception. Application authentication/ user application authentication
body: <p>I'm working on transforming my classic website to rest API in Symfony 2 world. </p>
  
  <p>First of all I'm doing that because I want to a mobile version of my project (maybe phone gap) but with angularjs. my question actually is what is the difference between my angular application authentication to access my api resources and the authentication of the users of the application. </p>
  
  <p>I'm working with Symfony2 standard edition, <code>Fosrestbundle</code>, <code>FosOauthbundle</code> and <code>Fosuserbundle</code> for user management and <code>JmsSerializerbundle</code> and <code>nelmio</code>.</p>
