title: Identity Server 4 with ASP.NET WebApi v1
body: <p>I've successfully integrated Identity Server 4 into asp.net MVC 4 project using OWIN/Katana middleware. But what about WebAPI v1?
  I've seen a statement in the web saying that "Web API v1 is not compatible with OWIN".</p>
  
  <p>Is it true? If so what is the other way to protect Api Resources?</p>
