I am testing azure B2C AD, I followed this tutorial: https://azure.microsoft.com/en-gb/documentation/articles/active-directory-b2c-devquickstarts-web-dotnet/
I have tested login with "local account" and Facebook everything is working perfect. I see that I can add a custom identity provider.
Can I add another Azure AD (not B2C) so that the users from that AD can login into my web application ?
