I still find the following text objectionable and confusing… By default, for historical reasons, unless an application-specific well-known URI path suffix is registered and used for an application, the client for that application SHOULD use the well-known URI path suffix "openid-configuration" and publish the metadata document at the path formed by concatenating "/.well-known/openid-configuration" to the authorization server's issuer identifier. As described in Section 5 <http://tools.ietf.org/html/draft-ietf-oauth-discovery-01#section-5>, despite the identifier "/.well-known/openid-configuration", appearing to be OpenID-specific, its usage in this specification is actually referring to a general OAuth 2.0 feature that is not specific to OpenID Connect.
Further, as a default “openid-configuration” as the default further gives people the impression that a plain OAuth server *is* an authentication server and that the normal access token received is evidence of a successful authentication. It would be better to point out that application may include oauth discovery in their discovery URI and that OAuth is an example of this. It might be good to include two examples. E.g. OIDC and SCIM (as another referenceable example). GET /.well-known/openid-configuration and GET /.well-known/scim Retrieve the OAuth configuration for the application openid and scim respectively. The use of: GET /.well-known/oauth2/ Should be the default used when there is no known application based well-known application based URI discovery. Of course, the concern I raised earlier is that this approach of application specific URIs ends up requiring every application to make an IANA registration if they don’t want to use the default of “oauth2” (or “openid-configuration”). Is that what the authors expect? It seemed better to me to use the webfinger syntax to allow the client to say “I want the designated OAuth configuration for the resource service X” would be a better design that avoids extensive IANA registration.
