title: Possible scenario with Thinktecture Identity Server?
body: <p>I have an ASP.NET SPA which is data driven by Web Api. It's using default login mechanisms at the moment. A future scenario is to do all communication from the web server to the backend over a queue (RabbitMQ).</p>
  
  <p>Then the simplified structure would looks like this:</p>
  
  <p>User logs on, data exchange is routed over the queue to a backend service. My question is now how make the backend aware if the requst is comming from an authenticated user?</p>
  
  <p>I found the Thinktecture STS and for what I know at the moment it looks very interesting. At least the web authentication should be no issue. but for now it looks to me as there is always a browser or a WCF service needed to do the authentication by the examples shown. There are no plans to use WCF or Azure on our site.</p>
  
  <p>Is it possible to transfer tokens the STS issued over a queue and let the consuming windows service be aware of what to do with these token?</p>
