title: ASP.NET MVC 4 Mixed authentication mode
body: <p>I am developing an MVC application that offers user two options for authentication:
  1- Windows Authentication
  2- Custom Authentication</p>
  
  <p>Based on user selection:</p>
  
  <p>1- If Windows, the username and password will be dimmed, application will use windows authentication.</p>
  
  <p>2- If custom, user enters username and password to get authenticated.</p>
  
  <p>Does this model work in ASP.NET MVC?</p>
  
  <p>Thanks</p>
