Doc Type: Known Issue
Doc Text:
The ipa-server-install and ipa-replica-install commands replace the list of NTP servers in the /etc/ntp.conf file with Red Hat Enterprise Linux default servers. As a consequence, NTP servers configured before installing IPA are not contacted, and servers from rhel.pool.ntp.org are contacted instead. If those default servers are unreachable, the IPA server does not synchronize its time via NTP. To work around this problem, add any custom NTP servers to /etc/ntp.conf, and remove the default Red Hat Enterprise Linux servers if required. The configured servers are now used for time synchronization after restarting the NTP service by running the systemctl restart ntpd.service command.

Description Arpit Tolani 2013-10-17 23:47:55 UTC
Description of problem:
When ipa-server-install or ipa-replica-install or ipa-client-install is run, it changes ntp.conf and add Red Hat NTP pool servers & remove existing servers.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:

Setup /etc/ntp.conf
Install ipa-server-install 

Actual results:

It will change existing values of /etc/ntp.conf

Expected results:

It should by default run as no ntp or should not change the value of existing servers, Just add below required parameter in ntp.conf


Additional info:

The change that the ipa-server-install forces is to point towards redhat's NTP servers, but that is a "default out of the box configuration" any way on any RHEL box. Why force that change on that manage their own NTP? And those that don't manage their own NTP, well they would already be pointing to RHEL NTP pool.

Is the -N/--no-ntp flag to ipa-server-install not adequate?

The ticket was triaged by the upstream and scheduled to later milestone. It is thus unlikely that the request will be finished in near future or in RHEL-6.x release. I am moving this Bugzilla to RHEL-7 product to narrow the expectations.
