RADIUS Test Option

It would be nice to be able to test and track radius server/s connectivity.

Hi, by test, do you mean a section in the web ui where you could put a username and password and run an authentication request against the radius server?

How would you like to track the radius server availability? What sort of notification are you thinking of?

I was thinking it would be nice to have a green light to show a successful connection to a radius server

yes the ability to enter authentication test information.
also the ability to trace the radius connection. ( as I have not yet been able to figure out why the remote sites can not connect to the radius server)

It would also be nice be able to connect to Active Directory directly.

I agree AD integration would be optimal.
However even a green light to validate radius connection, red light when disconnected and using local authentication.
