ldap timeouts not enforced for ldaps protocol

Description

According to site: https://bugs.php.net/bug.php?id=69574
I added LDAP_OPT_TIMEOUT to enforce bind operation time out. This worked for ldap protocol. But not for ldaps protocol.
steps to reproduce:

In one ssh session, I am running the following command to simulate a socket listener:
nc -l 636

And run following code:

<?php
$ldap = ldap_connect('ldaps://127.0.0.1:636');

ldap_set_option($ldap, LDAP_OPT_NETWORK_TIMEOUT, 3);
ldap_set_option($ldap, LDAP_OPT_TIMELIMIT, 3);
ldap_set_option($ldap, LDAP_OPT_TIMEOUT, 3);

ldap_bind($ldap);
?>

Resulted in this output:

This never times out

But I expected this output instead:

times out in 3 seconds. 

PHP Version

PHP 7.4.30

Operating System

Windows 10

Commencez par exécuter le script PHP fourni avec le listener nc et concentrez-vous sur les points d’entrée ldap_connect, ldap_set_option et ldap_bind pour le protocole ldaps. Suivez la manière dont LDAP_OPT_NETWORK_TIMEOUT, LDAP_OPT_TIMELIMIT et LDAP_OPT_TIMEOUT sont appliqués, puis vérifiez que le bind se termine avec un timeout après environ 3 secondes.
