I am totally new to the radius server aspect of authentication with cisco devices. I recently followed some instructions and setup the basic working structure of Radius NPS on a server 2008 r2 server. I haven't setup any groups or machines to authenticate to this server. The deal is I just want my cisco devices to authenticate with domain admin accounts (non cac card). So do I start now on my switches and router setting up AAA authentication etc? or do I need to do more to my server first. Like I said above, I haven't configured any groups or machines or anything beyond a basic Network Policy Server install.
