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 Petr Spacek 2014-11-07 14:28:43 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/bind-dyndb-ldap/ticket/144

This is a regression from RHEL 7.0.

DNS notify messages are not sent if modifications are made to zone names '''inside''' a zone.

By inside I mean e.g. name `test.idm.lab.eng.brq.redhat.com.` which part of zone `idm.lab.eng.brq.redhat.com`.

BIND should send `DNS notify` message when any object inside a zone is modified. This doesn't work in bind-dyndb-ldap 6.0+.

`Notify` messages are generated only if zone apex (`idm.lab.eng.brq.redhat.com.` in the example above) is modified.

Log message produced by BIND should look like this:
{{{
zone idm.lab.eng.brq.redhat.com/IN: sending notifies (serial 1415369834)
}}}
