printf in ppp auth.c disturbes xp server

[Ulrich Holeschak]

Hello, i am using win xp pro as l2tp server and rp-l2tp-0.3 als client. My pppd is ppp-mppe-2-4-0-4 (With microsoft authentication)   Now i have seen, that pppd sends some plain text messages over the netowrk during authentication like: "looking for secret in /etc/ppp/chap-secret" ...   But the XP server dislikes these telegrams very much and aborts the connection. So i have now removed all "printf" statements in auth.c of the pppd package and all works fine. But this seems to be not the optimum solution for me. Is there a different possibility?   Ulrich
