there is a dirty hack to retrieve original user id

http://graph.facebook.com/app-scoped-id this returns the facebook public information as follows, { "id": "app-scoped-id", "first_name": "xxxx", "gender": "male", "last_name": "yyyy", "link": "https://www.facebook.com/zzzz", "locale": "en_US", "name": "xxxx yyyy", "username": "zzzz" }

Then you make another graph api call with username http://graph.facebook.com/zzzz

This will returns the original facebook id and other public information, instead of app-scoped-id
