title: Single Sign On With thinktecture IdentityServer v2
body: <p>I'm running thinktecture IdentityServer v2 with two Relying Parties in my qa environment on Windows Server 2008 R2 Standard.</p>
  
  <p>IdentityServer is configured for two RPs, one using Federation the other with oAuth</p>
  
  <p>My first relying party (www.sitenumberone.com) is an ASP.Net Framework 4 web site using WIF Federation.</p>
  
  <p>My second relying party (www.sitenumbertwo.com) is an ASP.Net Framework 4.5 MVC 4 application using oAuth.</p>
  
  <p>When I attempt to access www.sitenumberone.com I am redirected to IdentityServer login and when I am authenticated I am redirected back to www.sitenumberone.com. This part works.</p>
  
  <p>My problem is, once I have authenticated to www.sitenumberone.com, if I try to hit www.sitenumbertwo.com I am redirected back to the IdentityServer login page. I would expect it not to redirect me back to the login because I have already authenticated.</p>
  
  <p>I have done some research and have not been able to find a solution to this problem. Do I need to set up www.sitenumberone.com as an oAuth client in IdentityServer?</p>
  
  <p>I hope someone can help.</p>
