<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Certification<o:p></o:p></p>
<p class="MsoNormal"> Roland managed to install all the software on the Symantec hosts<o:p></o:p></p>
<p class="MsoNormal"> We're missing the private keys for the certificates that they provided yesterday<o:p></o:p></p>
<p class="MsoNormal"> Don will be seeing them in 3 hours again and Mike and Roland will join them on a call<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Mike created initial certification pages at http://openid.net/certification/<o:p></o:p></p>
<p class="MsoNormal"> He asked people to review the content<o:p></o:p></p>
<p class="MsoNormal"> More specific submission instructions (including filenames, etc.) still need to be created<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Mike asked about the status of the dynamic registration tests<o:p></o:p></p>
<p class="MsoNormal"> Edmund wondered whether we need more tests for error cases, where the OP doesn't support things<o:p></o:p></p>
<p class="MsoNormal"> For instance, what if the client wants public subject values, but the OP can use pairwise values<o:p></o:p></p>
<p class="MsoNormal"> What actually will be done will be returned in the registration response<o:p></o:p></p>
<p class="MsoNormal"> People can propose tests but we won't do everything in phase 1 - some will come later<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Don had asked when we are going to lock down the test content and instructions<o:p></o:p></p>
<p class="MsoNormal"> We will do that a month before RSA<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Roland will put up the RP tests once rp.certification.openid.net is working<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Logout<o:p></o:p></p>
<p class="MsoNormal"> Mike posted two drafts of an HTTP GET based logout spec<o:p></o:p></p>
<p class="MsoNormal"> The second adds an id_token query parameter that is optional<o:p></o:p></p>
<p class="MsoNormal"> Microsoft engineers pointed out that there are security reasons not to pass an ID Token as a query parameter<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> John said that Google is interested in a back channel push logout to the relying party<o:p></o:p></p>
<p class="MsoNormal"> Mike pointed out that there would need to be a session identifier for that to work<o:p></o:p></p>
<p class="MsoNormal"> Google would put it in the ID Token<o:p></o:p></p>
<p class="MsoNormal"> They want to make it more useful for SAAS providers<o:p></o:p></p>
<p class="MsoNormal"> John and Adam are writing that up<o:p></o:p></p>
<p class="MsoNormal"> The front channel doesn't help you if you've lost your device<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> The Microsoft people pointed out they do cascading logouts with iframe gets<o:p></o:p></p>
<p class="MsoNormal"> They do image GETs to end nodes but iframe GETs to STSs<o:p></o:p></p>
<p class="MsoNormal"> John said that image GETs tend to be more parallelizable and reliable<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> George asked whether it was an option to use CORS support<o:p></o:p></p>
<p class="MsoNormal"> That would let you use POSTs<o:p></o:p></p>
<p class="MsoNormal"> The problem with that is the browser will execute those sequentially<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> John suggested that using an actual session ID is safer<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Let's use "sid" for the session identifier claim<o:p></o:p></p>
<p class="MsoNormal"> John said that Google had a different idea for what claim to use, but didn't remember what it was<o:p></o:p></p>
<p class="MsoNormal"> Virtual Device User Identifier<o:p></o:p></p>
<p class="MsoNormal"> Something that identifies an OP device/user agent pair<o:p></o:p></p>
<p class="MsoNormal"> Brian talked about the distinction between information usable as a session versus session identifiers<o:p></o:p></p>
<p class="MsoNormal"> John said that the session ID may be persistent<o:p></o:p></p>
<p class="MsoNormal"> SAML used SessionIndex for the same concept<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">OpenID Workshop on April 6<o:p></o:p></p>
<p class="MsoNormal"> https://openid-mar-2015.eventbrite.com<o:p></o:p></p>
<p class="MsoNormal"> We have the room all day<o:p></o:p></p>
<p class="MsoNormal"> We're currently scheduled to start at 11:00<o:p></o:p></p>
<p class="MsoNormal"> George has some proposals from working groups but not all of them<o:p></o:p></p>
<p class="MsoNormal"> Mike was wondering whether we'll actually need to start earlier, such as 10:00<o:p></o:p></p>
<p class="MsoNormal"> George will create an initial agenda and send it out for review<o:p></o:p></p>
