[pptp-server] CHAP authentication failed, what now?

[Dave Morse]

Hi,

I'm trying to configure a linux pptp client with windows 128 bit
encryption.  I've tried "dialing in", but /var/log/messages says "CHAP
authentication failed".  Any idea what to try now?

# pptp 111.11.11.11 user morse

/var/log/messages:
