I am planning to use Web Authentication (With External Server) on Cisco WLAN controller.
Unfortunately, I still do not have one with which I can experiment, and cannot find the following info in the documentation.
After a user authenticates successfully first time, when is authentication performed again?
Is that periodic? Or maybe specified in the Access-Accept message?
Thanks for your help.
I don't think anything is done in the background/transparant when the session timeout occurs.
If radius sends you a Session Timeout of 30 minutes, then at 30 minutes the WLC puts the client in a Web Auth Required state again. At which point, they will have to open Internet Browser and send the credentials again (manual process).
The session timeout is a hard-stop to force reauthentication....
The access-request/access-accepts (as far as I know) are only for the full authentication.
