End Google Ads 201810 - BS.net 01 --> Hi.

I'm developing a small Windows forms application on which I must apply logon security. I need to verify that the user exist in the AD, is part of a certain group and has the proper role.

I also need to take care of the fact that the computer might not be connected to the network hence no contact with the domain controller.

Does anyone have an idea on how to implement this in a simple way?
