[OAUTH-WG] draft-ietf-oauth-token-exchange/audience & draft-ietf-oauth-resource-indicators

[Hannes Tschofenig <[e-mail]>]

Hi all,

Token exchange registers the 'resource' parameter, at least to a large extend, and draft-ietf-oauth-resource-indicators indicates this in the IANA consideration section.

What isn't mentioned in draft-ietf-oauth-resource-indicators is that token exchange also defines the audience parameter. The audience parameter is defined as

"
Audience:
      The logical name of the target service where the client
      intends to use the requested security token.  This serves a
      purpose similar to the "resource" parameter, but with the client
      providing a logical name rather than a location.
"

I am mentioning this also because draft-ietf-ace-oauth-params defines a parameter 'req_aud', which was supposed to be similar to resource but at the last IETF meeting the argument was that it is a logical name. As such, it would correspond to the audience parameter registered in the token exchange.

Is my observation correct?

Ciao
Hannes
