I am working on converting the "IPP Authentication" slide set to a whitepaper. In the process, I've been considering OAuth a bit more. PWG 5100.18 (IPP Transaction Based Printer Extensions) defines the "oauth-authorization-server-uri", "access-oauth-token", and "access-oauth-uri" attributes. It isn't clear to me how these attributes integrate into an OAuth authentication system.
The way that OAuth / OAuth2 seems to work, there will be an HTTP response redirecting the User Agent (IPP Client) to a different server for authentication. If this is all handled at the HTTP layer, what value do these IPP attributes provide?
Thanks for any help,
