Radius + Credit card auth

  • I now have radius authentication working.
    I also have creditcard auth working

    But what I need to do now is figure out a way to get them both working at the same time.

    Heres the scenerio

    Members can enter in their username and password and gain access to the network/intarweb. If the user isnt a member then they have to pay $2 a day for access through the payment gateway.

    Whats happening now

    if I enable radius authentication the creditcard processing goes through, but then goes back to the authentication page (because there was no username supplied)

    any suggestions?

    I thought about adding a "creditcard" user to the radius, but i'm worried that someone will be able to nab that from the page source of the forum and use it for further access.
