Following up from the last Neutron meeting:<br>
<br>
If Neutron is performing an operation as an admin on behalf of a user that user's tenant-id (or project-id) isn't validated - in particular an admin can mistype and create object on behalf of non existent users. I am wondering how other projects (e.g. Nova)
deal with that and if there is some API support in keystone to save us a round trip (e.g. authenticate admin + validate additional user-id).<o:p></o:p></p>

<p class="MsoNormal">Not to long ago we got support in the auth_token middleware for a "service" token in addition to the user's token. The user token is sent in the x-auth-token header and the service token is sent in the x-service-token, and then fields from
both tokens are available to the application (e.g., the user project is in HTTP_X_PROJECT_ID and the service token roles are in HTTP_X_SERVICE_ROLES). So you could potentially have a policy rule on the server for the operation that required the service token
to have the 'service' role, and what neutron could do is send the original user token in x-auth-token and send its own token as the service token. This seems to be what you're asking for here.<br>
