title: ADFS 2.0, SSO and SAML 2.0
body: <p>This is a classic example of too much information = too much confusion.
  I have a ASP.NET web application that uses the usual POST form authentication and would like to implement SSO.
  Since we're a Microsoft shop we will use the ADFS 2.0. In order to implement SSO I understand that I will need to have also WIF to process SAML requests? 
  Do I install the WIF under the same server as the ADFS?</p>
  
  <p>I still want to re-direct failed SSO requests or non SSO requests to use the form, how do I handle this?</p>
  
  <p>Can someone please describe the flow?</p>
  
  <p>Thanks!</p>
