I thought I could configure freeradius with luci.
It seems am wrong?
Please tell me am not and direct me as to how to.
I don't believe that you can configure free radius with LuCI. There is no luci-app-freeradius or anything else that would indicate that there is a graphical interface for configuring and administering freeradius. Further, there is no mention of a GUI for it in the documentation (and most of the time, if there is a GUI option, you'll see at least some references/tutorials to that effect).
