>Subject: [PATCH] Ensure that in v2 auth tenant_id matches trust
>
>Previously if a trustee requests a trust scoped token for a project that
>is different to the one in the trust, however the trustor has the
>appropriate roles then a token would be issued.
>
>Ensure that the trust that was given matches the project that was
>specified in the scope.
