'Idle-Timeout' and the 'Acct-Session-Time' argument

[GNULinuxSlackware]

Hello,
I use :
-Ubuntu-server 7.10
-Freeradius 1.1.3
-Chillispot 1.0
-mysql 14.12

I have fixed an 'Idle-Timeout' argument into the "radgroupreply" MySQL table.
This works fine with the users in the group but the problem is that
"Idle-Timeout" doesn't report the logged out to "Acct-Session-Time".
So, in the "radacct" table, I can't see the user session is terminated.

What is the solution to close automatically the session in the
"radacct" table when there is an "Idle-Timeout" report?

Thanx a lot.
