I want to configure AD in my environment . currently we are working from home & whenever we want to connect our office network we connect vpn {OPENVPN}. Now we want to configure AD & if users are not connected to VPN in that situation also we want AD work & we can enforce policy also.
can you suggest how can I achieve this & what will be the best practice to make sure security as well. because may be we have to set our AD server on public platfrom.
