Good day.
We having troubles with the subject.
The issue is that with transparent autologon(TAL) there is no username in prepaid quota access-request packet, which makes impossible to unique user session identification. This is how access-request packet looks like in RADIUS debug:
rad_recv: Access-Request packet from host xx.xx.xx.222 port 1645, id=107, length=69
User-Password = "cisco"
Service-Type = Framed-User
NAS-Port-Type = Wireless-802.11
NAS-Port = 0
NAS-Port-Id = "SSG"
NAS-IP-Address = xx.xx.xx.222
So all quota request packets looks the same for RADIUS and it becomes impossible to give unique quotas for each user. There's no such issue with SESM for authentication, without TAL - quota reqest packets have username that way.
This is true for any software/harware combination we've tried so far(2811, 6500/7600, 7200 series, 12.2, 12.4 mainline, 12.4T, etc)
I'm not sure if this is a bug, or am I missing something?
