[pptp-server] authentication error

[Alan Chung]

I have installed pptp server and compiled kernel modules as installation 
guides.  It seems working but I got some kind of authentication error about 
chap when I tried to connect to server from 98 client.

My /etc/options file looks like

lock
debug
name lemon
auth
require-chap
+chap
proxyarp
+chapms
+chapms-v2
mppe-40
mppe-128
mppe-stateless

and my /etc/chap-secrets looks like

# Secrets for authentication using CHAP
# client                server          secret          IP addresses
temp                    lemon           admin           *

ps. temp is the client's hostname and admin is the username I use to 
connect to server.
     lemon is the pptpd server's hostname.


The following is the log message I got and does anyone have a clue?
