RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
When install ipa-server or ipa replica, they replace on /etc/ntp.conf server configured previusly by hand/user to this server:

### Added by IPA Installer ###
server 0.rhel.pool.ntp.org
server 1.rhel.pool.ntp.org
server 2.rhel.pool.ntp.org
server 127.127.1.0
fudge 127.127.1.0 stratum 10

Version-Release number of selected component (if applicable):
[root@ipaserver ~]# rpm -qa | grep ipa
ipa-python-3.0.0-37.el6.x86_64
ipa-pki-common-theme-9.0.3-7.el6.noarch
ipa-admintools-3.0.0-37.el6.x86_64
libipa_hbac-1.9.2-129.el6.x86_64
ipa-server-3.0.0-37.el6.x86_64
ipa-pki-ca-theme-9.0.3-7.el6.noarch
ipa-server-selinux-3.0.0-37.el6.x86_64
libipa_hbac-python-1.9.2-129.el6.x86_64
python-iniparse-0.3.1-2.1.el6.noarch
ipa-client-3.0.0-37.el6.x86_64
[root@ipaserver ~]#

How reproducible:
Always

Steps to Reproduce:
1. configure ntp.conf to point to your closest ntp server (intranet or internet server)
2. install ipa server or ipa replica


Actual results:
ipa server replace ntp server on ntp.conf

Expected results:
no change anymore ntp server

Thanks for the report. This is currently a known issue, tracked in Bug 1020563. Note that if you want to avoid IPA server touching NTPD at all, you can use --no-ntp option. Then the configuration should not be replaced.

Closing as duplicate so that we can track the fix in one place.
