[pptp-server] Two quickees...

I just confirmed that you can use PAP with pptpd.  My client machine was
Windows 2000, and I configured it to custom security settings with no
encryption and only PAP authentication enabled.

Note that I compiled pptpd using --with-pppd-ip-alloc so I specify the IP
address to assign (192.168.1.99) in pap-secrets, instead of using the pool
of addresses in /etc/pptpd.conf


------ /etc/pptpd.conf --------
debug
option /etc/ppp/options.pap
-------------------------------
------ /etc/ppp/options.pap ---
debug
kdebug 1
name gateway
mru 1450
mtu 1450
auth
require-pap
proxyarp
192.168.1.20:
-------------------------------
------ /etc/ppp/pap-secrets ---
phil gateway secret 192.168.1.99
-------------------------------
