title: Deploy ADFS 2.0 login page to ADFS 3.0?
body: <p>I have set up a ADFS 3.0 server on Windows Server 2012 R2.
  To satisfy the requirement, I need to customize the default login page (not only the UI, but the validation logic).
  Since ADFS 3.0 is not allow me to customize the login page, I decide to write the login page myself.</p>
  
  <p>I decide to extract the source code of ADFS 2.0 login page, and deploy it to IIS as my new login page. Is it possible?</p>
  
  <p>Or please provide some information on customizing the ADFS 3.0 login page. </p>
