The radius protocol only supports processing of authentication requests.
Unless you can get your hardware to send a periodic re-auth request,
there's no way to have them processed by radius again no matter what
you do to the database. Radius has no "push" capability.
Your options are:
+ Get your hardware to re-auth periodically.
+ Use another process to boot users (forcing a reauth) when you
change the database.
