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.

Fixed In Version: ipa-4.6.4-10.el7_6.2
Doc Type: Bug Fix
Doc Text:
Previously, the automember commands assumed existence of a hostgroup with the same name as the automember rule. As a consequence, when an automember rule was using a deleted hostgroup, the "ipa automember-rebuild --type=hostgroup" command failed to execute and exited with an "Automember rebuild task aborted" error message. With this update, Identity Management in Red Hat Enterprise Linux provides a new command "ipa automember-find-orphans --type=hostgroup" that allows to find the automember rules that have a missing host. The command provides a "--remove" option that deletes such automember rules. As a result, if you run "ipa member-find-orphans --type=hostgroup --remove" before calling ipa automember-reuild, automember-rebuild succeeds.

automember rebuild crashed. When deleted the hostgroup rule manually, it started working.

Thus based on above observations, marking it as Failed_QA.
Comment 4 Florence Blanc-Renaud 2019-01-17 09:34:02 UTC 
The fix delivers a new command, ipa automember-find-orphans --type={hostgroup,group} [--remove]

When "ipa automember-rebuild --type hostgroup" fails, you should run the new command to find/remove the orphans. The verification steps should be modified to use this new command.
Comment 5 Mohammad Rizwan 2019-01-17 09:45:31 UTC 
Steps:

1. ipa hostgroup-add test

2. ipa automember-add --type hostgroup test

3. ipa automember-add-condition --key=fqdn --inclusive-regex=^replica[1-9]+\.testrelm\.test test

4. ipa dnsrecord-add --a-ip-address=10.16.200.69

5. ipa host-add replica1.testrelm.test

6. ipa automember-rebuild --type hostgroup

7. ipa hostgroup-del test

8. ipa automember-rebuild --type hostgroup

9. ipa automember-find-orphans --type=hostgroup --remove

10. ipa automember-rebuild --type hostgroup

Rebuild got succeed after running "$ipa automember-find-orphans --type=hostgroup --remove" when it crashed.

Thus based on above observations, marking the bug as verified.
