    Hi ng,

    anyone practicing ISDN ppp callback using RADIUS Authentication
    via Microsoft IAS ? I do have the following setup on a 2611XM.

    The radius is working properly via * VPN * , meaning a PIX 501 behind the
    is coupled with it do deliver the proof that IAS itself is OK.
    Now, I can dial in and authenticate via Radius/IAS, everything just fine.
    But when adding callback commands on the Dialer I get rejected
    ("--> Callback not authorized for user xyzwhattheheck --> Disconnect" )

    I assume I am missing certain radius / IAS read-out values, because checking
    the appropiate boxes
    within IAS ( Callback negotiation control ) does not bring me further. I
    would like
    to have the user data on the IAS including Callback-Dialstring and such.

    Any hints highly appreciated.
