I know not traditional that using on-premise active directory (Local AD) for public services, but I don't have alternative that has AD's features. For example many software that integrated with AD.
I want know active directory is good choice for using as authentication/authorization/account solution in a website? (For public services)
Note: I don't give permission to public users that they can access directly to AD. It is possible use the ADFS between AD and public users.
