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.

Description Vaidas Jablonskis 2011-10-06 16:33:03 UTC 
Description of problem:

Current version of openldap-servers-2.4.19 in RHEL6.0 uses embedded berkeley db version 4.8.x. After an update to RHEL6.1, openldap-servers gets updated to 2.4.23 which does not have berkeley db embedded and uses system-wide db4 which is v4.7.

So basically if you have openldap running and using bdb backend db on RHEL6.0 and you update the system to RHEL6.1 the slapd starts to complain that the DB environment is actually newer than the application which is trying to access it.


Version-Release number of selected component (if applicable):

openldap-servers-2.4.23

How reproducible:

every single time


Steps to Reproduce:
1. install openldap-servers-2.4.19
2. create a database, import some data
3. update openldap-servers to 2.4.23
4. the update process will try to restart a slapd service, but it will fail


Actual results:
ldap.log when trying to start slapd 2.4.23:
--
Oct  6 12:11:26 lada slapd[15593]: bdb(dc=foo,dc=com): Program version 4.7 doesn't match environment version 4.8

Oct  6 12:11:26 lada slapd[15593]: bdb(dc=foo,dc=com): txn_checkpoint interface requires an environment configured for the transaction subsystem
Oct  6 12:11:26 lada slapd[15593]: bdb_db_close: database "dc=foo,dc=com": txn_checkpoint failed: Invalid argument (22).
Oct  6 12:11:26 lada slapd[15593]: backend_startup_one (type=bdb, suffix="dc=foo,dc=com"): bi_db_open failed! (-30971)
Oct  6 12:11:26 lada slapd[15593]: bdb_db_close: database "dc=foo,dc=com": alock_close failed
Oct  6 12:11:26 lada slapd[15593]: slapd stopped.

Expected results:

I expect the RHEL6.1 also include upgrades for db4 to 4.8.x or some technique on how to downgrade an openldap db files to 4.7.x version of db4.

Comment 2 RHEL Program Management 2011-10-07 16:02:11 UTC 
Since RHEL 6.2 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

Comment 4 Jan Vcelak 2012-02-07 09:29:00 UTC 
OpenLDAP was shipped with embedded libdb, which was no good from security reasons. We removed it during OpenLDAP rebase between RHEL6 and RHEL6.1. System libdb is used now.

Please, export your database before upgrade, and reimport it back after the upgrade. And we are sorry for the inconvenience.
