problem with callback

[labis siegfried]

i have a little problem, my router (cisco 3640) with his configuration 
without radius authentification do the callback normally, but with radius 
authentification, the connection is without callback, the radius server 
have this instruction :
login  Auth-type := Local, Password == "pass"
         Service-Type = Callback-Framed-user,
         Service-Type = Callback-Framed,
         Service-type = Callback-Login-user,
         Framed-Protocol = PPP

but i can't find where is the error
