[pptp-server] MPPE works with chapms, not chapms-v2

[Kim Armann]

Hi Josh,

I have no problems :
pppd[1582]: MSCHAP-v2 peer authentication succeeded for ******
pppd[1582]: Script /etc/ppp/auth-up finished (pid 1583), status = 0x0
pppd[1582]: rcvd [CCP ConfReq id=0x4 <mppe 1 0 0 a1>]
pppd[1582]: sent [CCP ConfNak id=0x4 <mppe 1 0 0 60>]
pppd[1582]: rcvd [IPCP ConfReq id=0x5 <addr 0.0.0.0> <ms-dns1 0.0.0.0> 
pppd[1582]: sent [IPCP ConfNak id=0x5 <addr 10.254.254.103>
<ms-dns192.168.85.1> <ms-wins 192 .....
....

I'm using Kernel 2.4.2 (upgraded from 2.4.1, pppd-2.4.0) Windows 2k SP1
(SP1 is not really needed)

here is my options file :
noauth
crtscts
lock
asyncmap 0
nodetach
lcp-echo-interval 45
lcp-echo-failure 4
idle 720
noipx
ms-dns 192.168.85.1
ms-wins 192.168.85.1
auth
lock
debug
+chap
+chapms
+chapms-v2
mppe-128
mppe-40
mppe-stateless
nodeflate
nobsdcomp
