My wireless APs are currently running 29.6.1. On some of my networks, I've notice that my aps are sending Accounting-Stop much earlier than they are supposed to. On my MAB ssid, I have a captive portal set up to send a disconnect request after successful login. This is when I'm used to seeing Accounting-Stop (after Disconnect-Ack). Since the stop is being sent too early, (directly after MAB authentication) my radius server assumes they have already disconnected, so it's not sending a disconnect to the AP.
Has anyone seen this? I have a ticket open, but I'm curious.
