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 Gowrishankar Rajaiyan 2012-03-22 10:14:26 UTC

Description of problem:


Version-Release number of selected component (if applicable):
ipa-server-2.2.0-5.el6.x86_64

How reproducible:
Always

Steps to Reproduce:
1. ipa-server-install --setup-dns
2. ipa dnszone-find

Actual results: 
"SOA serial" for forward zone has just "YYYY".

[root@primenova ~]# ipa dnszone-find

  Authoritative nameserver: primenova.lab.eng.pnq.redhat.com.

  Active zone: TRUE
  Allow query: any;

----------------------------
Number of entries returned 2

Expected results:
SOA serial for forward zone after installation should be of the format "YYYMMDDnn".

Additional info:
This is not seen for any new zone created thereafter.

Comment 3 Gowrishankar Rajaiyan 2012-03-22 11:42:52 UTC

Just observed that "SOA expire" value is trimmed as well.

Comment 4 Martin Kosek 2012-03-22 13:50:12 UTC

I found out that this is not really an issue in IPA, it created the forward zone correctly but it got changed by nsupdate/bind-dyndb-ldap backend which is run as a part of ipa-client-install. This can be easily reproduced this way:

Comment 6 Petr Spacek 2012-03-23 12:20:38 UTC

LDAP plugin part fixed upstream:
https://fedorahosted.org/bind-dyndb-ldap/changeset/709e352e52141eac346139666483b5c5f5acd713

Wrong initial value has to be fixed in IPA.
