I haven't heard of azp before (was focusing just on the basic and implicit
Just read the spec and from what I understand "azp" would be in my example
the "aud" of the id_token generated by the delegation endpoint. But I'm not
sure. The definition of "Authorized Presenter" is kind of ambiguous to
me. Is it the party that "presents" the token, the caller? Sorry if I'm
missing something obvious.
- What is the difference between having multiple audiences vs using azp?
- In the scenario I describe there is claims
transformation/mapping/augmentation, so it's not enough with just adding
the "azp" to the original id_token, which takes me to the next point
- Maybe this is subject to a different spec. But as an implementer, what
I would like to see is the protocol flow for the delegation scenario (kind
of like what I wrote in the email). The "azp" claim sounds like a small
part of that.
