title: Authorization with AD groups
body: <p>I'm wondering how could I apply a way to give a specific groups on Active Directory the access to the website published internally on IIS.</p>
  <p>As I understand since I'm working with core 3.1; this must be done by code inside the application.
  and that the web config not needed anymore.</p>
  <p>any help/hint/advice would be appreciated.</p>
  <p>Regards</p>
