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).

Description Patrik Kis 2013-05-24 13:55:21 UTC

+++ This bug was initially created as a clone of Bug #961244 +++

If realm join was done via adcli, and not 'net ads join' then 'realm leave --remove' doesn't actually remove the computer account from the domain.

Comment 1 Stef Walter 2013-07-22 14:01:17 UTC

Fix pushed to realmd and adcli git master.

Comment 2 Patrik Kis 2013-08-12 12:55:13 UTC

Hi Stef,
i'm afraid there is still a bug in this fix; it seems adcli command with leave --remove is not complete.

Comment 3 Stef Walter 2013-08-12 13:00:56 UTC

Hmmm. I think you need to use adcli 0.7.2 or later. I released these two together. Did adcli 0.7.2 not make it into RHEL 7.0?

Oh, yes, I should have tried that, it just looked like pure realmd problem.
I'll check with the newest adcli.
