Re: [OAUTH-WG] OAuth & Protected feeds

Darren, As an OAuth 2 provider and consumer as well as someone who's preparing to build the DiSo interactions my proposal was based on, I would prefer a single flow that addresses what I feel will be a increasingly common set of requirements rather than combining two flows designed for two distin

James, This example illustrates that OAuth2 discovery needs to let a service explicitly indicate whether a direct and/or user-delegation flow is required. For instance, a "WWW-Authenticate: OAuth2" response could define 2 parameters: 'user-uri' and 'token-uri'. If only one is present, only the co

Re: [OAUTH-WG] Extensibility: new endpoints

I'm fine with specifying OAuth discovery in an additional I-D/RFC (along with the extension I have asked for). As a consequence, does this mean you will remove all references to OAuth Discovery from the core specification? Beside that, this raises another question: Are there additional functiona

I mean address as in "uniquely label". Based on your explanation I assume you address resources instead of resource servers. Correct? What parameter of the end-user authorization flow is used to indicate the resource URL to the authz server. The scope? regards, Torsten. Am 02.08.2010 um 02:1

Yes, that's correct, as HTTP adopts the definition of 'absoluteURI' from the URI specification itself. It's just in the protocol itself that fragments are not sent. >From RFC2616: "This specification adopts the definitions of "URI-reference", >"absoluteURI", "relativeURI", "port", "host","abs_p

Re: [OAUTH-WG] resource server id needed?

The "scope flow" is intended to carry this information, and the authz manager/server compares the requested scope to a known mapping of protected resources to resource servers. (We're still working out details, and also trying to keep up with the changes to the OAuth2 substrate...) Eve

Hi Oleg, If you want to send an access token directly to the server, we have the web server flow designed to do that. The JS redirect or Ajax call is just a more complicated way to send the token to the server. The user-agent flow is intended for use where the resource needs to be accessed dire

The single assertion use case is well defined. If you need to support multiple assertions in a single request, you will need to define a way to group them together and include them using the single assertion parameter or define an extension for additional assertions. Either way, this sounds like
