title: Azure B2C authentication and admin login
body: <p>we currently work on site that uses Azure B2C authentication for "normal" public users. The site has an admin backend that need "admin" users login. How do you do that? In azure B2C we can't have groups to identify which is an Admin. Can I use custom attributes like Admin-Boolean and set it to true in the Azure users portal? It is secure enough?</p>
