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.

pkgdiff report between openldap-2.4.46-11.el8_1 and openldap-2.4.46-15.el8

Created attachment 1740171 [details]
pkgdiff report between openldap-2.4.46-11.el8_1 and openldap-2.4.46-15.el8

Description of problem:
We are running an installation of apache httpd (2.4.46) where we compile it and bundle compiled versions of openssl (1.1.1i) and modsecurity (2.9.3). 
It has been running fine in several different environments on both RHEL 7 and 8 as well as CentOS 7 and 8.

The other day, it suddenly started failing with the following error message when loading modsecurity:

    httpd: Syntax error on line 251 of httpd.conf: Cannot load modules/mod_security2.so into server: /lib64/libldap-2.4.so.2: undefined symbol: EVP_md2, version OPENSSL_1_1_0

Our investigations shows that this started happening when openldap was bumped from openldap-2.4.46-11 to openldap-2.4.46-15 during a regular system update.

I'm not competent enough in these matters to say if this is a bug with the release of the package or not, just hoping that you might be able to shed some light on it.


Version-Release number of selected component (if applicable):
openldap-2.4.46-15.el8

How reproducible:
Always


Steps to Reproduce:
1. System running with our httpd package
2. Upgrade openldap-2.4.46 from release 11 to 15

Actual results:
httpd syntax error on startup

    httpd: Syntax error on line 251 of httpd.conf: Cannot load modules/mod_security2.so into server: /lib64/libldap-2.4.so.2: undefined symbol: EVP_md2, version OPENSSL_1_1_0

Expected results:
No syntax error on startup and a running system


Additional info:
Not sure if useful, but I've attached the output of pkgdiff between the mentioned releases.
