title: Oauth2 in Symfony2
body: <p>I'd like to use some APIs, foursquare for example, in my Symfony2 project. The problem is that instead of the 2 great FOS bundles concerning Twitter/Facebook, I'm not finding anything on OAuth (I tried the EtcPasswdOAuthBundle but did not manage to make it work because of a missing file I guess).</p>
  
  <p>Moreover, I'd like to make it work with FOSUserBundle.</p>
  
  <p>So, if you could give me some help, I do not understand how to manage OAuth with Symfony ...</p>
  
  <p>Thanks !</p>
