When I worked at SirusXm and we had RHEL, we had lots of issues with RHEL ‘secure LTS versions’ not having the right dependencies for newer bleeding edge stuff. In fact, RHEL stable was almost 1-2 years behind for some things.
Check with your RHEL IT team and ask them to look into.
This may not be a Postgres thing, but a RHEL issue.

<snip> checking for HMAC_CTX_new... yes checking for HMAC_CTX_free... yes checking for CRYPTO_lock... no checking for ldap_bind in -lldap... no configure: error: library 'ldap' is required for LDAP
we have: openldap-2.4.46-18.el8.x86_64
Bug: it does not recognize the presence of openldap.
Note: yes I did not try 15.3. We have an approval process that makes obtaining 15.3 not trivial. But 15.3 release notes do not mention ldap so I expect bug to be in 15.3 too. Can anyone confirm issue please?
