<p class="MsoNormal">Introductions<o:p></o:p></p>
<p class="MsoNormal"> Rifaat is a product manager at Auth0/Okta. This is his first Connect call.<o:p></o:p></p>
<p class="MsoNormal"> Roland Hedberg is an independent consultant and author of OpenID Connect Federation<o:p></o:p></p>
<p class="MsoNormal"> Giuseppe is in the Department of Digital Transformation for the Italian Republic<o:p></o:p></p>
<p class="MsoNormal"> Thomas is a researcher working for Fraunhofer in Germany and interested in SIOP<o:p></o:p></p>
<p class="MsoNormal"> David is now at Crossword Cybersecurity. They implemented the TRAIN infrastructure from Fraunhofer.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Federation Repository<o:p></o:p></p>
<p class="MsoNormal"> The Federation work has moved to the Connect Bitbucket repository (off of Roland's GitHub repository)<o:p></o:p></p>
<p class="MsoNormal"> Mike will create a pull request migrating the one small set of changes only present in Roland's repository<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Federation Issues<o:p></o:p></p>
<p class="MsoNormal"> #1382: Proposal of an improved Federation API<o:p></o:p></p>
<p class="MsoNormal"> Giuseppe spoke in favor<o:p></o:p></p>
<p class="MsoNormal"> This aligns with #1387: Operations -> endpoints<o:p></o:p></p>
<p class="MsoNormal"> Roland is in favor of the refactoring<o:p></o:p></p>
<p class="MsoNormal"> David is in favor of the refactoring as it aligns with TRAIN<o:p></o:p></p>
<p class="MsoNormal"> Tom said that you need to stay within the same origin to get cookies<o:p></o:p></p>
<p class="MsoNormal"> The working group wants a pull request that does this refactoring<o:p></o:p></p>
<p class="MsoNormal"> #1368: [federation_api] fetch entity statement - issuer paramenter is really required?<o:p></o:p></p>
<p class="MsoNormal"> Waiting on a security review by John Bradley<o:p></o:p></p>
<p class="MsoNormal"> #1384: Trust Negotiation<o:p></o:p></p>
<p class="MsoNormal"> Mike is concerned about having entity statements return information about things other than the subject<o:p></o:p></p>
<p class="MsoNormal"> Roland said that this is about the "evaluate entity statement" operation<o:p></o:p></p>
<p class="MsoNormal"> He said that the Italian implementation wants to be able to ask one part what they think of the other<o:p></o:p></p>
<p class="MsoNormal"> This generalizes the existing functionality<o:p></o:p></p>
<p class="MsoNormal"> It returns metadata, not an entity statement<o:p></o:p></p>
<p class="MsoNormal"> Mike observed that you could have an operation that walks trust chains<o:p></o:p></p>
<p class="MsoNormal"> or walk the trust chains yourself<o:p></o:p></p>
<p class="MsoNormal"> David said that TRAIN has an operation to ask whether a party is a member of the federation<o:p></o:p></p>
<p class="MsoNormal"> Giuseppe said that the operation would be optional<o:p></o:p></p>
<p class="MsoNormal"> Roland said that it can be more efficient to have a third party do it<o:p></o:p></p>
<p class="MsoNormal"> We agreed that the operation and its goals need to be more clearly specified. That's the next step.<o:p></o:p></p>
<p class="MsoNormal"> #1391: Clarifications and proposals on Trust Negotiation<o:p></o:p></p>
<p class="MsoNormal"> This proposes terminology clarifications/unification<o:p></o:p></p>
<p class="MsoNormal"> Giuseppe will make a list of proposed changes in the issue<o:p></o:p></p>
<p class="MsoNormal"> #1366: Support for "immediate" exclusion of an entity from a federation<o:p></o:p></p>
<p class="MsoNormal"> This would add a revocation operation<o:p></o:p></p>
<p class="MsoNormal"> It would give an operation to check whether an entity is still part of the federation<o:p></o:p></p>
<p class="MsoNormal"> The trust anchor could issue a new kind of trust mark and have an operation to test inclusion<o:p></o:p></p>
<p class="MsoNormal"> Roland said that it's simpler than introspection<o:p></o:p></p>
<p class="MsoNormal"> He said that it's also similar to what the TRAIN project is doing<o:p></o:p></p>
<p class="MsoNormal"> Giuseppe said that having a trust mark could have benefits<o:p></o:p></p>
<p class="MsoNormal"> Tom said that any trust should be able to be tested in the moment<o:p></o:p></p>
<p class="MsoNormal"> Giuseppe said that they don't need to do dynamic checking each time<o:p></o:p></p>
<p class="MsoNormal"> You should be able to cache results<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Pull Requests<o:p></o:p></p>
<p class="MsoNormal"> <a href="https://bitbucket.org/openid/connect/pull-requests/">
https://bitbucket.org/openid/connect/pull-requests/</a><o:p></o:p></p>
<p class="MsoNormal"> PR #105: Trust Negotiation<o:p></o:p></p>
<p class="MsoNormal"> This is related to issue #1384<o:p></o:p></p>
<p class="MsoNormal"> Tom says that this appears to violate the zero trust model<o:p></o:p></p>
<p class="MsoNormal"> Roland says that the operation could be used to determine whether to do the evaluation yourself<o:p></o:p></p>
<p class="MsoNormal"> We agreed that the operation and its goals need to be more clearly specified. That's the next step.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">PKCE and Certification Question<o:p></o:p></p>
<p class="MsoNormal"> #1362: alignment of certification tests with OAuth 2.1<o:p></o:p></p>
<p class="MsoNormal"> Mike said that the suite already checks that PKCE usage doesn't cause failures<o:p></o:p></p>
<p class="MsoNormal"> Joseph confirmed that<o:p></o:p></p>
<p class="MsoNormal"> Joseph said that requiring PKCE at the OP would break any RPs not using PKCE, which is the majority<o:p></o:p></p>
<p class="MsoNormal"> Mike said this would be a breaking change, bifurcating our ecosystem<o:p></o:p></p>
<p class="MsoNormal"> We ran out of time at this point and agreed to continue discussing the topic<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Next Call<o:p></o:p></p>
<p class="MsoNormal"> The next Connect call will be Monday, January 17, 2022 at 3pm Pacific Time<o:p></o:p></p>
