<p class="MsoPlainText">Hi,<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I’m working on the Swift implications of using composite authorization [1] [2].<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">My question for Keystone developers is : what project-id do we expect the service token to be scoped to - the service's project or the end-user's project? When reviewing the Keystone spec, I had assumed the former. However, now that
I'm looking at it in more detail, I would like to check my understanding.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">The implications are:<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">1/ If scoped to the service's project, the role used must be exclusive to Glance/Cinder. I.e. an end-user must never be assigned this role. In effect, a role on one project grants the service user some privileges on every project.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">2/ if scoped to the end-user's project, the glance/cinder service user must have a role on every project that uses them (including across domains); this seems infeasible.
<o:p></o:p></p>
