That's one of the requirements to be RESTful, is it not? In OAuth's case, the resource and the authorization server are usually tightly coupled. (Otherwise, you need another specs like UMA.) So, the resource server should be able to tell either the location of the authz endpoint. In some trusted environment, the resource may as well return the location of the authz server configuration data. In these cases, you do not have to decide on what .well-known uri as you say. This frees up developers from configuration file location collisions etc. We should strive not to pollute the uri space as much as possible. > (well, except if there are several ASs each with different scopes; sounds > like an edge-case to me though; maybe RFC6750 should instead be updated > with such a parameter such that an RS could return several > WWW-Authenticate: Bearer, each with its own "scope" and "duri" value?) > Yeah, I guess it is an edge case. I would rather like to see these authz servers to develop a trust framework under which they can agree on a single set of common scope parameter values.
