Additional feedback on the introspection endpoint.
What is the expected error response if the introspection endpoint is
using client credentials as recommended in section 2.1
The endpoint SHOULD also require some form of authentication to
access this endpoint, such as the Client Authentication as described
in OAuth 2 Core Specification [RFC6749
<http://tools.ietf.org/html/rfc6749>] or a separate OAuth2 Access
Token.
and the client credentials are invalid. It doesn't seem correct to
return an HTTP 200 with a body of { "valid: false } as the endpoint
probably never even tried to validate the token parameter.
I can see a couple of options...
1. Follow the RFC 6749 /token endpoint and return an HTTP 40X response
with the error described in JSON in the body of the response.
2. Follow RFC 6750 and return a WWW-Authenticate Response header that
contains the error and optionally error_description.
Thanks,
George
