Custom domain and federated login

[mafrost]

Hello, I'm trying to do a federated login and it works fine locally and on ***.appspot.com but not when I add my custom domain, it gives the following error:

1. That’s an error.

OpenID auth request contains an unregistered domain: ***

When reading up a bit about this it seems as if openid-support will be removed from google services. Maybe you should make oauth standard instead in this project? Am I missing something?
