[pptp-server] PoPToP and Authentication Questions

[Cowles, Steve]

To answer your question regarding NT Domain Authentication... The answer is
yes and no (I know!!!)

Let me explain:

No... PopTop (itself) does not authenticate you against your NT PDC. Its
role is to authenticate your PPTP/pppd encrypted session (tunnel) through
the use of CHAP. This requires a separate username/password entry on the
linux box running PopTop. <groan>

Yes... Once your PPTP tunnel is established, your client PC running
Win98/WinNT will be able to authenticate to the PDC. Obviously, the
authentication will not occur until the tunnel is brought up. This of course
requires PopTop/pppd to be setup properly and a functional WINS server on
the local LAN so that once the tunnel is brought up, the client PC can
obtain the PDC record from the WINS server. Samba really has nothing to do
with the authentication process unless your using it as a WINS server or a
PDC.

The topic of being able to have pppd authenticate against a MS PDC has been
brought up before in this list. I must admit, it would be nice. I know I
don't like having to maintain two sets of username/passwords on each system.
