Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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 Oliver Falk 2019-04-02 14:21:47 UTC 
Description of problem:
I had the issue that the AD admins removed the DNS records and nobody noticed, until some "strange" issue appeared. I already guessed that the DNS records could be affected and checked them. However, since there are some to check, I though eventually there is a subcommand like dns-check-system-records, analogous to dns-update-system-records. Unfortunately, that is not the case.

Version-Release number of selected component (if applicable): ipa-client-4.6.4


How reproducible: Always


Steps to Reproduce: n/a

Actual results:
ipa doesn't have dns-check-system-records command.


Expected results:
ipa hould have dns-check-system-records command for an easy way to check if all dns records are correct.

Moving this to RHEL 8
Comment 7 Rob Crittenden 2019-11-19 20:06:20 UTC 
Fixed upstream in master:
95dbb7ff70d686f93a0230532c02eb8969ab8a16

This checks the equivalent of:

ipa dns-update-system-records --dry-run

It only checks the first resolver that answers on the current system.
