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-2.2.0-3.el6
Doc Type: Bug Fix
Doc Text:
Cause: IPA server uninstall process removed system users that were added as a part of IPA installation. This included dirsrv or pkiuser users which are Directory Server use to run its instances. These users also own log files produced by Directory Server. Consequence: If IPA server was being installed again and the newly added system users UID changed, the Directory Server may fail to start because the Directory Server instance is not permitted to write to the log files owned by the old system user with a different UID. Fix: System users generated by IPA server installation are no longer removed in uninstall. Result: System users UID does not change and new Directory Server configured by the new IPA server installation process is able to write to its log files.

Description Dmitri Pal 2012-02-26 18:08:51 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/freeipa/ticket/2423

When we run ipa-server-install --uninstall we remove the user we create to run 389-ds as, dirsrv.

The problem is if you install IPA, uninstall it, then create a new system user that user will get the old dirsrv uid and file permissions will be such that trying to re-install IPA will fail with:

CRITICAL failed to restart ds instance Command '/usr/sbin/setup-ds.pl --silent --logfile - -f /tmp/tmpSm39vT' returned non-zero exit status 1
