In a corporate environment shared key encryption is rarely used due to the problems associated with distributing the appropriate keys. In the corporate wireless world many organisations prefer to use 802.1x or Radius authentication so that their users can log on to the wireless networks with their domain credentials.
I was recently asked to set up just s system with Unifi access points and controllers on Windows Server 2012 with Microsofts own Radius solution NPS (or Network Policy Server) and 802.1x. There is plenty of information out there but I found that some of it was out of date and others were missing some fairly key components. So I present this tutorial to hopefully helps others get this up and running as quickly as possible.
