Restricting Multilink ppp connections.

Hi there,

does anyone know how to restrict dial up users for using multilink PPP based on their RADIUS profile?? We are using RADIUS from Potal and AS5300 running 12.2(5) (c5300-is-mz.122-5.bin). I have tested using local authentication succesfully, but when a turn aaa to RADIUS, it doesnt work. Only is possible to get one connection. This is the aaa config of my Access Server:

aaa group server radius MODEMS

server ip_radius_server_1 auth-port 1645 acct-port 1646

server ip_radius_server_2 auth-port 1645 acct-port 1646

aaa authentication ppp default group MODEMS none

aaa authorization exec default local none

aaa authorization network default group MODEMS none

aaa authorization network restricted group radius

aaa accounting delay-start

aaa accounting update newinfo

aaa accounting network default start-stop group MODEMS

aaa accounting connection default start-stop group MODEMS

Any help will be appreciated.

Thanks in advance for your help.
