My use case is that when a user requests that they want to take a action on the platform (i.e.: boot a VM) they aren't also using that same token to load a image in Glance or delete another VM, etc.</div><div><br></div><div>How would I do that or is that even possible?</div><div><br></div><div>Thanks a lot!</div><div>-Brian</div></body></html>
