(RADIATOR) Cisco 4402 Session-Timeout Issues

I have a Cisco wireless controller (the 4402). I have 2 standard WLAN's
configured on it, one authenticates off of LDAP via RADIUS using WPA
stuff...one is wide open and uses a portal for authentication purposes.
This of course will be used for any vendors who come to visit the
company. The problem I am seeing is the following..
I would like to limit the Vendors session to a specific amount of time.
I am sending back a "Session-Timeout" to the user, and its being applied
as at times the session will timeout at the given interval. I say at
times because there are other cases when the device will send an
"Interim" accounting packet...and then my session will terminate exactly
the "Session-Timeout" + Acct-Session-Time that was sent in the interim
packet. It seems like the Wireless controller is resetting the
"Session-Timeout" to the original value once it receives an ACK for any
interim accounting packets.
Is this the proper behavior of Session-Timeout? Or is this 4402 code
from Cisco flawed? Any ideas?
