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 of problem:
Currently, RHEL 9 has OpenLDAP 2.4 version.
Fedora 36 has OpenLDAP 2.6 version, which is already being tested by other packages for a few months.
Full ABI Compatibility Report between 2.4 and 2.6: https://spichugi.fedorapeople.org/ol_24_26_abi_check/compat_report.html

We need to rebase OpenLDAP to 2.6.2 version in RHEL 9.1.

This update unexpectedly broke build of RHEL-9 curl packages.  I just discovered it while I was working on a security update of curl:

make[2]: Leaving directory '/builddir/build/BUILD/curl-7.76.1/build-full/lib'
../../lib/openldap.c:83:17: error: conflicting types for 'ldap_connect'; have 'CURLcode(struct Curl_easy *, _Bool *)'
   83 | static CURLcode ldap_connect(struct Curl_easy *data, bool *done);
      |                 ^~~~~~~~~~~~
In file included from ../../lib/openldap.c:39:
/usr/include/ldap.h:1555:1: note: previous declaration of 'ldap_connect' with type 'int(LDAP *)' {aka 'int(struct ldap *)'}
 1555 | ldap_connect( LDAP *ld );
      | ^~~~~~~~~~~~


I am backporting the following upstream commit to fix it:
