[OpenID] claims vs scopes vs extra

[John Bradley]

There is a specific interop Google Group/list https://groups.google.com/forum/#!forum/openid-connect-interop

That is the best place to discuss bugs in the tests.  

Those claims make the most sense if the response is signed.   However they should not cause a fail if unsigned.

I suspect that you are the only person returning those so it is probably a bug in the test.   Contact the list and we will try and get it sorted out.

Specifically in regards to the response content to the UserInfo endpoint. It’s very clear from the specification that if I request a particular scope, what standard claims should be returned. Likewise, if a specific claim is requested then that claim is to be returned. Any extra claims about the user also would not be returned.

So to me that appears inconsistent in behavior. After figuring this out, I went reading through the core document and couldn’t find an answer either way. There is a reference in 5.3.2 that the response SHOULD contain iss and aud if it is signed or encrypted. I’m not actually doing either (yet).
