Description of problem:
(This bug should be filed under dhclient. However, dhclient is missing
from Bugzilla. So I file it here).
dhclient writes a ntp.conf file for NTP which contains the line
However, since 4.2.0, ntp mo longer supports the "authenticate"
command which results in
Dec 26 16:52:16 localhost ntpd: configure: keyword
"authenticate" unknown, line ignored

authentication is activated by default now, but the manual _should_
mention, that the popular "authenticate no" line to enable simple
network broadcasting no longer works, but must be replaced by
Then multicast and broadcast for time will work again.
However, dhclient should write a correct ntp.conf file (omitting the
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Launch an DHCP client host where the DHCP server reports an NTP host
2. Look at the /etc/ntp.conf file
3. Look at the daemon syslog file
Actual Results: No errors
Expected Results: See above.
$ rpm -qif /sbin/dhclient|fgrep Source
Group : System Environment/Base Source RPM:
This problem is fixed in dhclient-3.0.1-14, which has been in
FC4/rawhide for nearly a month now.

does not remove local clock server entries.
I'm kicking off the process of pushing it to FC3 upgrades .
Meanwhile, you can download it from:
Latest version is now dhcp-3.0.1-16, with the NTP (and other) fixes.
