[ntp:questions] notrust alternative?

That was my problem all along. My server is Mandriva 2007 Free, and I'm using the version of ntp that is included with the distro,
4.2.0 at 1.1161-r. In /etc/sysconfig/ntpd the -A option is enabled by default. I removed that and took out 'enable auth' in my
ntp.conf, restarted ntpd, and now everything works the way David Mills says it should.
Now the question...why would Mandriva disable authentication by default?? After what David Mills has said, and what I've been
dealing with, that seems rather insecure.
Thanks a lot Ronan for pointing this out. I feel embarrased for not noticing it was running with the -A option by default. I just
didn't pay attention. But hopefully this will help someone else out.
Thank you everyone for the help,

| Also check that ntpd is not started with the -A option, which is another
