title: .net mvc Windows authentication to multiple ad domains
body: <p>I have an application that needs users  to authenticate from two domains: A and B.
  The application is an .net MVC 5 application using windows authentication</p>
  
  <p>It is established one-way trust between the domains, and I have tested the trust, so it should be all good. The application is deployed on domain A, so I have noe problem with users from that domain. </p>
  
  <p>However, when I try to log on from the other domain, I am promted with a logon-box and a 401 error message.</p>
  
  <p>Are there any configuration steps I am missing to get the solution working?</p>
