Radius (IAS) to limit users access

Hi Guys, i am using microsoft IAS server remote user policies to limit the amount of data a user can download and to shape their bandwidth etc…

its all working great except once a user has reached their download quota and get booted off the system, they can just relog in again and their quota has been reset.

is there anything i can do to keep this from happening. i.e so that they cant just log back in and continue using the service.

thanks in advance.

you have to write you own script which on each authorization request will count how much traffic they could still download. If it’s reached reject the user. I don’t know how to do this on Miscrosoft IAS. But on Freeradius this can be done.

can you tell me how this is done on freeradius, may be i might be able to apply the same principals to IAS.

thanks

i’m storing all the data in the data base. On each authentication request i’m executing one attribute which counts from this DB how much MB(GB)are left for the user who is authenticating.
