We will have tablets running Win 8.1 Pro that will be joined to the domain, and users will sign in to those devices with their network credentials; however, I don't anticipate them connecting to the network via VPN while on the road. Instead, I expect the app to hit our remote DP on the DMZ, which in turn would talk to our internal app server behind the firewall. So it is a 4-tier deployment. In in this context, will I have access to their identify when sending requests to the remote DP?
In other words, can I utilize ApplicationContext.User in the domain-joined WinRT world? Or should I expect to require the user to enter his credentials in the app itself and pass them (over https) with every call to the remote DP for authentication on the server? Thanks.
