Radius Integration Problem

[iesreza]

Environment:

• ntopng edge v.6.3.240904 (Ubuntu 20.04.6 LTS)

What happened: We noticed several issues with NTOPNG integration with RADIUS. 1- NTOPNG disconnects the users and change the group into captivepass after about 30 minutes of inactivity. This behaviour happens when the user is still present on the network but does not do any internet traffic. we already asked to remove auto disconnect in #8728

2- We have introduced a radius proxy to fill the consumption tracking gap regarding to #8706 and during integration we have noticed NTOPNG reports wrong pool (group) for some devices while do Interim Update on radius. In the provided example the user pool is gnvcrewstar while in the packet as provided marked as captivepass.

3- Changing the pool (group) from dashboard does not trigger any RADIUS accounting request.
