Is it possible for an OpenVPN client to log into a Windows AD domain on the server end of the tunnel?
In my set up, my OpenVPN server is running on a linux box joined to the domain and I'm using the centrifyDC package to authenticate OpenVPN client against the AD domain. Clients can access all the domain resources - they are prompted to provide their domain credentials when they attempt to access a resource.
That's all fine, but when a client accesses SQL Server via SSMS, when they select 'Windows Authentication' they can't independently supply their domain credentials; they need to be logged into the domain for this to work.
Ideally, I would be able to do this transparently when they log in to OpenVPN.
