vpn poptop

Bonjour, j'ai installe un serveur vpn pptp : poptop
tout a bien marche en 5 minutes... j'ai recompile un pppd avec les patchs
pour le mschapv2 et le module noyau ppp-mppe pour le cryptage. sauf que je
ne peux pas me connecter en demandant le cryptage.... seul une connection en
CHAP, SCHAP, MSCHAP, MSCHAP-v2 marche, mais sans le cryptage.
voici les logs que j'obtiens a ma connection, peut etre pouvez vous les
comprendre mieux que moi : (en piece jointe, pour eviter les retours
chariots)
