<p class="MsoNormal">Hi all,<o:p></o:p></p>
<div>
<p class="MsoNormal">We discussed an important topic on the call today, and some of us had separately discussed this earlier. There are a couple of issues with the draft today:<o:p></o:p></p>
</div>
<div>
<ol start="1" type="1">
<li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1">
The use of "common claims" e.g. "spag_id" conflicts with the Subject Identifiers draft that specifies claims other than those defined within the "subject_type" definition must not be included in a subject claim of that subject_type.<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1">
We defined a specific "user-device-session" subject type, but are now discovering use cases that create a multitude of other possibilities. The immediate one that caused this discussion was the use of an "application" principal. The use case is where a Transmitter
may want to invalidate sessions associated with a specific application on a specific user or device.<o:p></o:p></li></ol>
<div>
<p class="MsoNormal">To address both these issues, Tim Cappalli (Microsoft) and I came up with this proposal to create multi-valued or "compound" subject claims in SSE events. This will not require the use of common claims such as "spag_id", but we can create
specific new subject_types such as "tenant" or "OU" as needed.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>

here</a>. It will be great if you can provide your comments and feedback in the next couple of weeks so that we can have a productive discussion in our next call on March 2nd. If we can make sufficient progress in the call there, we can incorporate the changes
into the draft.<o:p></o:p></p>
