First there was a sid. The sid alone is not enough (if the same value is used among RPs in the same session), therefore you need to introduce an audience and a digital signature. This is getting more complex with every iteration.<br>
<br>
>From a conceptual perspective, the challenge we are facing is the OP wants to send a request to a protected resource (logout endpoint at the RP). Sounds familiar? Yes, because this is classic OAuth with the OP taking the role of the client. <br>
<br>
I would therefore suggest to let the RP register the token it wants to get its logout endpoint invoked with. One could also use RFC 6750 mechanisms (or even pop) to carry the token in the actual logout request. The advantage of this design: this token is opaque to the OP. There is no need to specify it. The token design and how to identify the respective session at the RP is at the RP's discretion. It could just be a reference to its session database. It also could be a JWT.<br>

My point was not that audience was not needed, but rather that it could be a different audience to differentiate between the login and sign out tokens.<div class="">That WAY the sign out tokens would not be accepted as login tokens. eg the logout_uri rather than the client_id as a posable example.<div class=""><br class="" /></div><div class="">John B.</div><div class=""><br class="" /><div class=""><div><blockquote type="cite" class=""><div class="">On Feb 23, 2015, at 6:32 PM, Mike Jones <<a href="mailto:Michael.Jones@microsoft.com" class="">Michael.Jones@microsoft.com</a>> wrote:</div><br class="Apple-interchange-newline" /><div class=""><div class="WordSection1" style="page: WordSection1; font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px
