Re: [OAUTH-WG] Proposed Syntax Changes in Dynamic Registration

Further to my last…

Justin has already committed to breaking changes.  This may have been lost or buried in the long review thread.

Specifically - The client authentication types specified are undocumented (client_secret_jwt and private_key_jwt) as they were all Holder-of-Key authentication methods.  The OAuth drafts currently only have bearer drafts and dyn reg does not support these profiles.  Justin has acknowledged this.

It seems to me, that since the token_endpoint_auth_method is broken, the current implementations are actually implementing the draft correctly or servers are just ignoring it the parameter.

There are concerns with this draft.  I plan to make specific suggestions (some breaking) later this week.

Those deployments demonstrate that the spec, as written, is already doing one thing well – enabling clients (as defined by RFC 6749) to register with Authorization Servers, obtaining client_id and optionally client_secret values that enable those clients to use those Authorization Servers.  Doing one thing well is exactly what we should be striving for, and the evidence says that we’ve achieved that.

Speaking as the editor: "A" is the default as far as I'm concerned, since we shouldn't change syntax without very good reason to do so. That said, if it's going to be better for developers with the new parameter names, I am open to fixing them now.
