Hi,
I installed freeradius and configured it with LDAP and  installed pptp also in debian lenny. I can login to radius server from windows and I have VPN connection and internet.
Now I want to restrict my VPN users' bandwidth and internet charge(for example 4G charge for each user), but I don't know how to do it with freeradius+LDAP.

I would be grateful if you can answer me as soon as possible.
Regards,
