[Openid-specs-ab] Identifiers and discovery.

[Breno de Medeiros]

I hope Nat's well.

I was in a meeting at 3:00pm (that I scheduled after JBradley asserted
the conference call would take place as usual at 4pm). When I joined,
Mike Jones and Nat were dropping off the call.

That left JBradley and I on the call. We had a discussion on
identifiers and discovery.

I would like to continue this conversation via email, as it's an important one.


Currently, Google's proposal on identifiers is:

- Identifiers are unique to the user and non-reassignable within the
scope of the issuer. However, they need not be globally unique.

- Id_tokens attest to the issuer and therefore provide a statement of
the globally unique (issuer_id, user_id) pair. If the signature is
based on PK, these tokens are also universally verifiable and fully
portable.

Looking forward to an interesting discussion,
