Thank you for the replies. I will work with my team to get these RADIUS servers setup with our internal CA in our windows domain. I do have multiple RADIUS servers (one at each of 12 sites and 2 at the Data Centers for backups). I will get all of them added to our CA since it will depend on which switch and location the user will use for RADIUS. This is just for wired so far, I still have wireless 802.1x to setup and test.
