--- Comment #1 from Mohammad S. Babaei <info at babaei.net> ---
I have to mention that my certificate for the OpenLDAP has been issued by Let's
Encrypt and is not self-signed if it makes any difference (because I saw the
following changes) on the release note:

https://ftp.openbsd.org/pub/OpenBSD/LibreSSL/libressl-3.2.4-relnotes.txt

We have released LibreSSL 3.2.4, which will be arriving in the
LibreSSL directory of your local OpenBSD mirror soon.

It includes the following bug and interoperability fixes:

    * Switch back to certificate verification code from LibreSSL 3.1.x. The
      new verifier is not bug compatible with the old verifier causing issues
      with applications expecting behavior of the old verifier.

    * Unbreak DTLS retransmissions for flights that include a CCS

    * Only check BIO_should_read() on read and BIO_should_write() on write

    * Implement autochain for the TLSv1.3 server

    * Use the legacy verifier for autochain

    * Implement exporter for TLSv1.3

    * Free alert_data and phh_data in tls13_record_layer_free()

    * Plug leak in x509_verify_chain_dup()

    * Free the policy tree in x509_vfy_check_policy()

The LibreSSL project continues improvement of the codebase to reflect modern,
safe programming practices. We welcome feedback and improvements from the
broader community. Thanks to all of the contributors who helped make this
release possible.
