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: openldap-2.4.44-15.el7_5
Doc Type: If docs needed, set a value
Doc Text:
Previously, during an OpenLDAP server upgrade, CA certificates were sometimes not extracted correctly due to SELinux policies not having been upgraded yet at the time. Consequently, the OpenLDAP server did not start after the upgrade as expected, and the administrator had to remove the /tmp/openldap-tlsmc* directories manually for the server to start. This update ensures that slapd correctly recreates the CA certificates. As a result, the OpenLDAP server starts correctly in the described scenario.

Description Oneata Mircea Teodor 2018-04-03 07:01:12 UTC 
This bug has been copied from bug #1547922 and has been proposed to be backported to 7.5 z-stream (EUS).
Comment 4 Patrik Kis 2018-04-12 07:51:07 UTC 
The test with upgrade from RHEL-7.3 proved that the issue was mitigated.
During the upgrade the server certificate files in tmp directory could not been created, but the temporary certificate directory was not lefty in inconsistent state so manual restart of the slapd daemon restored the service.
