<p class="MsoNormal">Errata and Issues<o:p></o:p></p>
<p class="MsoNormal"> #968 - Inconsistent treatment of id_token_hint<o:p></o:p></p>
<p class="MsoNormal"> Mike will apply the proposed resolution and then have people review the result<o:p></o:p></p>
<p class="MsoNormal"> #970 - Core - 2 - ID Token acr claim incorrectly specifies the level 0 of assurance<o:p></o:p></p>
<p class="MsoNormal"> John still needs to take a stab at new wording saying what "0" meant historically<o:p></o:p></p>
<p class="MsoNormal"> #973 - Core 2 / 3.1.3.7 - azp claim underspecified and overreaching<o:p></o:p></p>
<p class="MsoNormal"> We got data on what Google is actually doing with "azp"<o:p></o:p></p>
<p class="MsoNormal"> Notably, it is not used in an OpenID Connect protocol flow<o:p></o:p></p>
<p class="MsoNormal"> Brian's comment "Rather Connect should strive for something that's consistent and easily comprehensible" seems dead on<o:p></o:p></p>
<p class="MsoNormal"> Mike will take a stab at slightly revised wording following Brian's suggestions<o:p></o:p></p>
<p class="MsoNormal"> John suggests that RPs reject tokens with "azp" unless they understand what is going on<o:p></o:p></p>
<p class="MsoNormal"> #974 - Deprecated algorithm RSA1_5 used in spec examples and self-issued<o:p></o:p></p>
<p class="MsoNormal"> We should clearly change the examples<o:p></o:p></p>
<p class="MsoNormal"> Self-issued is a more intricate issue<o:p></o:p></p>
<p class="MsoNormal"> Mike suggests that we're probably better off deprecating singing and encrypting with the same key<o:p></o:p></p>
<p class="MsoNormal"> John says that encrypting to the client is an edge case<o:p></o:p></p>
<p class="MsoNormal"> You can only do this upon the second interaction with the provider!<o:p></o:p></p>
<p class="MsoNormal"> #975 - Do we add additional related specifications?<o:p></o:p></p>
<p class="MsoNormal"> Mike will do<o:p></o:p></p>
<p class="MsoNormal"> #976 - Unregistered openid2_realm and openid2_id<o:p></o:p></p>
<p class="MsoNormal"> Mike will prepare text that registers these values.<o:p></o:p></p>
<p class="MsoNormal"> #977 - How to handle an unsupported response_mode?<o:p></o:p></p>
<p class="MsoNormal"> John pointed out that if you don't support the response_mode, you can't even return error and error_description<o:p></o:p></p>
<p class="MsoNormal"> Therefore, we'll return 400.<o:p></o:p></p>
<p class="MsoNormal"> #978 - URL for errata<o:p></o:p></p>
<p class="MsoNormal"> Mike documented our existing practice in the bug<o:p></o:p></p>
<p class="MsoNormal"> We should probably make a blog post saying how other specs can reference current versions and specific versions, as makes sense in their use cases.<o:p></o:p></p>
<p class="MsoNormal"> We could explicitly put language about URLs for the current and this versions in the spec, like the W3C does<o:p></o:p></p>
<p class="MsoNormal"> #979 - Discovery / Security Considerations: CSRF attack on user input identifier<o:p></o:p></p>
<p class="MsoNormal"> We need to work out how to prevent MITM attacks against Dynamic Registration<o:p></o:p></p>
<p class="MsoNormal"> The attack is getting someone to talk to a bad token endpoint<o:p></o:p></p>
<p class="MsoNormal"> You don't know that you've registered at the right endpoint when you register<o:p></o:p></p>
<p class="MsoNormal"> This issue clearly needs discussion on the mailing list.<o:p></o:p></p>
<p class="MsoNormal"> One possible fix is to have registration return the token endpoint URL for a cross-check<o:p></o:p></p>
<p class="MsoNormal"> Mike points out that in multi-tenant environment, the issuer will vary by tenant<o:p></o:p></p>
<p class="MsoNormal"> We may want to look at how we're using the JWT token profile<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> See the "Discovery Endpoint CORS support?" e-mail thread<o:p></o:p></p>
<p class="MsoNormal"> Mike will file an issue about this<o:p></o:p></p>
<p class="MsoNormal"> You need CORS support for JavaScript clients<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> People should add any other errata issues to the tracker at<o:p></o:p></p>
<p class="MsoNormal"> https://bitbucket.org/openid/connect/issues?status=new&status=open<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Workshop before IIW<o:p></o:p></p>
<p class="MsoNormal"> People are registering<o:p></o:p></p>
<p class="MsoNormal"> http://www.eventbrite.com/e/openid-foundation-workshop-before-fall-2015-iiw-meeting-tickets-17960843366<o:p></o:p></p>
<p class="MsoNormal"> Nat needs to be removed from the agenda since he won't be able to attend<o:p></o:p></p>
<p class="MsoNormal"> Roland will be there and will do live RP test demonstrations<o:p></o:p></p>
<p class="MsoNormal"> Mike will ask Don if "HMG Cabinet Office Chairs" is correct for HEART<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Workshop after IETF 94 Yokohama<o:p></o:p></p>
<p class="MsoNormal"> http://www.eventbrite.com/e/openid-summit-tokyo-2015-tickets-18111127871<o:p></o:p></p>
<p class="MsoNormal"> Registration is not yet open for that<o:p></o:p></p>
<p class="MsoNormal"> Registrations may actually happen on a different Japanese page<o:p></o:p></p>
<p class="MsoNormal"> Nat translated the Japanese event page to English at http://j.mp/cfp_oid15<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Certification<o:p></o:p></p>
<p class="MsoNormal"> Roland fixed some RP certification bugs but his WebFinger responses use https://localhost:8080/<o:p></o:p></p>
<p class="MsoNormal"> Edmund has reported this to Roland<o:p></o:p></p>
<p class="MsoNormal"> Roland is officially back from vacation tomorrow (Tuesday)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Next Call<o:p></o:p></p>
