Angry NTP problems: authentication

My ntp.conf file:

restrict default noserve nomodify
driftfile /etc/ntp/drift
authenticate yes
keys /etc/ntp/keys
trustedkey 1

My keys file:

1 M 12345678

My step-tickers file:

My problem:

I have a Stratum 1 NTP server on I can connect to it and get the time with no problems. However I am required to use MD5 authentication, and I can't set it up. No matter what I try, even if I disable authentication or change the keys, or anything else - I am able to get the time from the server. It seems like nothing is being hashed at all, just like normal NTP request/reply.

Any suggestions?


Update: used Ethereal, found out that the NTP packets are being sent as without authentication... but I've done everything possible to make it authenticate!!
