I have seen some posts on the Stack Overflow that, Endpoints will not work with Google Accounts Authentication. I have also tried and it does not work. This means, if you are using UserServiceFactory for authentication, and then make endpoints call through a javascript client , then a User object in the server-side is null. You cannot recreate a valid User object.
