Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.
- OpenLDAP server with 'dds' overlay configured and olcDDStolerance is set.
- The dynamic entries are deleted before their TTL is expired. olcDDStolerance is shortening dynamic entries TTL, instead of its prolonging.
- The patch was applied to correctly evaluate real time of dynamic entries deletion.
- The dynamic entries real lifetime is entry's entryTtl + olcDDStolerance as described in documentation

Slapd configuration file
Description of problem:
DDS overlay tolerance parametr doesn't function. Default ttl parametr work bad with set dds-tolerance. EntryTtl attribute has right value, but entry is delete before ttl expiration.
Version-Release number of selected component (if applicable):
openldap-servers-2.4.23-15.el6
How reproducible:
always
Steps to Reproduce:
1.slaptest -f /etc/openldap/slapd.conf -F /etc/openldap/slapd.d/
(slapd.conf is in attachement)
2.add entry
dn: cn=OpenLDAP Documentation Meeting,ou=Meetings,dc=my-domain,dc=com
objectClass: groupOfNames
objectClass: dynamicObject
cn: OpenLDAP Documentation Meeting
member: cn=testusr1, dc=my-domain,dc=com
member: cn=testusr2, dc=my-domain,dc=com
3.sleep 120
4. ldapsearch -LLL -x -b 'cn=OpenLDAP Documentation Meeting,ou=Meetings,dc=my-domain,dc=com' \"(objectClass=dynamicObject)\"
Actual results:
Entry cn=OpenLDAP Documentation Meeting,ou=Meetings,dc=my-domain,dc=com doesn't exist after 120s (lifetime should be entryTtl + tolerance = 240s). Even entry doesn't exist after 30s.
Expected results:
Entry should be exist after 120s.

proposed patch
olcDDStolerance setting had inverse effect and in fact was shortening entries real TTL. Attaching patch. It will be submitted upstream.
Technical note added. If any revisions are required, please edit the "Technical Notes" field
accordingly. All revisions will be proofread by the Engineering Content Services team.
