Dereference client id document as described in Solid-OIDC spec

[AbelVandenBriel]

While testing an application, we tried to send an authorization request to solidcommunity.net (which runs on the NSS I believe) while using a client id that pointed to a. client id document as described in section 5 and 5.1 of the solid OIDC spec.

This resulted in an Unauthorized error. I tried the exact same request with a dynamically registered client and it worked, so it seems that solidcommunity.net (and therefore the NSS) don't yet support these client id documents.

I was unable to find any issues pertaining to this in either repo.

Am I correct in assuming this is not implemented yet?

I think this is related to the fact that NSS doesn't support the latest solid OIDC spec, see #1510 and #1639
