<p class="x_MsoNormal">Hi all,</p>
<div>
<p class="x_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:</p>
</div>
<div>
<ol start="1" type="1">
<li class="x_MsoNormal" style="">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.</li><li class="x_MsoNormal" style="">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.</li></ol>
<div>
<p class="x_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.</p>
