title: LinkedIn Authentication on OWIN/MVC5
body: <p>We've used LinkedIn OAuth/Simple membership on MVC4 project, and it is working pretty.</p>
  
  <p>But with inspecting new OWIN based ASP.NET MVC5 framework, we found there is no LinkedIn authentication feature. We could use Google,Facebook,Twitter and Microsoft live ID, but no LinkedIn.</p>
  
  <p>Are there any kinds of simple ways to integrate the LinkedIn authentication into new OWIN/Katana/MVC5?</p>
