title: SuppressDefaultHostAuthentication in WebApi.Owin also suppressing authentication outside webapi
body: <p>I am running into a problem with a solution where I used parts from the Visual Studio SPA template for having the Account Controller in WebApi with Oauth Authentication.</p>
  
  <pre><code>  app.UseOAuthBearerTokens(OAuthOptions);
  </code></pre>
  
  <p>Then I in the owin webapi registration is doing  </p>
  
  <pre><code>config.SuppressDefaultHostAuthentication(); 
  </code></pre>
  
  <p>but this also supresses the default cookie authentication outside the webapi environment. Is this the intention. If so, how can I set up WebApi to supress cookie authentication but its still active accross the environment for other requests?</p>
