[pptp-server] pppd + pptp + radius

There are two solutions.

1.  Using PAM and one of the two PAM RADIUS modules, authenticate via
    RADIUS (one module is pam-lradius, the other is in the base PAM

    Caveat: this doesn't get static IPs from RADIUS or do accounting
            via RADIUS.

2.  Using one of the two PortSlave distributions, do authentication,
    IP address allocation, etc from RADIUS.  Combined with something
    gated, this can mean your users can authenticate via either the VPN
    or a dialup NAS and get the same IP address.  Accounting is also via
    RADIUS as per dialup NAS's.

    Caveat: you may need to look at the code carefully to ensure
            traffic accounting and run an exact version of pppd.  I
            ever tried using a PortSlave PPPd and adding the MSCHAP

I've done both of these at different places I've worked as well as using
a third option - authenticating via a Bay ERPCD.
