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.

Comment 3 Martin Kosek 2012-03-02 15:07:16 UTC 
I found the reason why this issue happens. We call acutil.res_send() to send a DNS query to find A record of the new hostname. However, the request may not be sent to the current resolver in /etc/resolv.conf but to the old one that was configure there before. Which apparently does not know this hostname.

So if you run ipa-dns-install and then tried this use case right after it, it resulted to this error. As a workaround, one can reload httpd process after ipa-dns-install.
Comment 4 Jenny Severance 2012-03-02 15:13:52 UTC 
I installed the ipa-server with --setup-dns ... why should I have to run ipa-dns-isntall ?
Comment 5 Jenny Severance 2012-03-02 15:21:24 UTC 
however, fresh install behaves the same, see acceptance tests results when they come in on list.
Comment 6 Martin Kosek 2012-03-02 15:37:00 UTC 
Oh, its the same with --setup-dns. The problem is in change of /etc/resolv.conf and unability of acutil to realize it.
Comment 7 Rob Crittenden 2012-03-12 19:22:00 UTC 
Fixed upstream.

master: c956b3cd2ba12d87054909af3dce7d231f034240

ipa-2-2: 453dbdc0dd412ed90950f10ffd8be895ff7b2ded

This was addressed by restarting Apache after configuring bind so it gets an updated resolv.conf.
