[THIN] Question on RDP and clients

We’ve got a Citrix web interface and secure gateway on PS 4.0. What we’d like to do and have been experimenting with is RDP connections from a user’s home PC for example to their desktop at work. The concept works, however, security wise the client has to be configured to only allow that particular user to access their specific desktop. A handful of users have successfully done this, however the caveat here is that each client has to be touched. Curious if anyone has deployed something like this on a larger scale and how they’ve overcome the administrative overhead.
