how to disconnect user after quota given to him finishes ?

[Rupesh Amatya]

Dear all,
I am using Freeradius(with mysql as database for users ) with 
Mikrotik as NAS. This for PPPOE users. I used Dialup Admin to manage 
freeradius.

There is default package of 4hours/day but the users do not get 
disconnect after 4 hours. It just shows " Out of Quota". What needs 
to be done to automatically disconnect user after the daily quota is 
finished ?


Hope to get help .....

Thanking  you
