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: 389-ds-base-1.3.7.5-21.el7_5
Doc Type: Bug Fix
Doc Text:
In a Directory Server replication topology, updates are managed by using Change Sequence Numbers (CSN) based on time stamps. New CSNs must be higher than the highest CSN present in the replica update vector (RUV). In case the server generates a new CSN in the same second as the most recent CSN, the sequence number is increased to ensure that it is higher. However, if the most recent CSN and the new CSN were identical, the sequence number was not increased. In this situation, the new CSN was, except the replica ID, identical to the most recent one. As a consequence, a new update in the directory appeared in certain situations older than the most recent update. With this update, Directory Server increases the CSN if the sequence number is lower or equal to the most recent one. As a result, new updates are no longer considered older than the most recent data.
