Re: [OAUTH-WG] OAuth Milestone Update and Rechartering

[Anthony Nadalin <[e-mail]>]

There are folks that are not implementing connect for various reasons (i.e. security reasons, complexity reasons, etc.). thus this is compatible with connect if folks want to move on to connect,  we surely don’t use connect everwhere as it’s over kill where we only need a the functionality of a4c.

Can you point to one publicly available or publicly documented implementation of a4c?    I've never seen one.

I will say the a4c spec is almost 100% overlapped with OpenID Connect.   Some minor variations in claim names, but it adds 0 incremental value over what we have in Connect.

Connect is being successfully deployed at large scale.  It would be irresponsible for this working group to confuse developers and the industry with duplicate work, especially given this feels more like an argument over signing IPR agreements.

I agree with Phil on this one, there are implementations of this already and much interest

On the contrary. I and others are interested.

We are waiting for the charter to pick up the work.

Regardless there will be a new draft shortly.

I would object to 'OAuth Authentication' being picked up by the WG as a work item. The starting point draft has expired and it hasn't really been discusses since Berlin nearly a year ago.  As I recall, there was only very limited interest in it even then. I also don't believe it fits well with the WG charter.

I would suggest the WG consider picking up 'OAuth Symmetric Proof of Possession for Code Extension' for which there is an excellent starting point of http://tools.ietf.org/html/draft-sakimura-oauth-tcse-03 - it's a relativity simple security enhancement which addresses problems currently being encountered in deployments of native clients.

Hi all,

you might have seen that we pushed the assertion documents and the JWT
documents to the IESG today. We have also updated the milestones on the
OAuth WG page.

This means that we can plan to pick up new work in the group.
We have sent a request to Kathleen to change the milestone for the OAuth
security mechanisms to use the proof-of-possession terminology.

We also expect an updated version of the dynamic client registration
spec incorporating last call feedback within about 2 weeks.

We would like you to think about adding the following milestones to the
charter as part of the re-chartering effort:

-----

Nov 2014 Submit 'Token introspection' to the IESG for consideration as a
Proposed Standard
Starting point: <draft-richer-oauth-introspection-04>

Jan 2015 Submit 'OAuth Authentication' to the IESG for consideration as
a Proposed Standard
Starting point: <draft-hunt-oauth-v2-user-a4c-01>

Jan 2015 Submit 'Token Exchange' to the IESG for consideration as a
Proposed Standard
Starting point: <draft-jones-oauth-token-exchange-00>

We also updated the charter text to reflect the current situation. Here
is the proposed text:

Charter for Working Group


The Web Authorization (OAuth) protocol allows a user to grant a
third-party Web site or application access to the user's protected
resources, without necessarily revealing their long-term credentials,
or even their identity. For example, a photo-sharing site that
supports OAuth could allow its users to use a third-party printing Web
site to print their private pictures, without allowing the printing
site to gain full control of the user's account and without having the
user share his or her photo-sharing sites' long-term credential with
the printing site.

The OAuth 2.0 protocol suite encompasses

* a protocol for obtaining access tokens from an authorization
server with the resource owner's consent,
* protocols for presenting these access tokens to resource server
for access to a protected resource,
* guidance for securely using OAuth 2.0,
* the ability to revoke access tokens,
* standardized format for security tokens encoded in a JSON format
  (JSON Web Token, JWT),
* ways of using assertions with OAuth, and
* a dynamic client registration protocol.

The working group also developed security schemes for presenting
authorization tokens to access a protected resource. This led to the
publication of the bearer token, as well as work that remains to be
completed on proof-of-possession and token exchange.

The ongoing standardization effort within the OAuth working group will
focus on enhancing interoperability and functionality of OAuth
deployments, such as a standard for a token introspection service and
standards for additional security of OAuth requests.

Feedback appreciated.
