Default-Search path for ldap.conf changed to D:\a\winlib-builder\winlib-builder\install\etc\openldap\ldap.conf

[HoffmannTom]

Description

The following code:

<?php
ldap_set_option(NULL, LDAP_OPT_DEBUG_LEVEL, 7);
$conn = ldap_connect("ldaps://ldap-server-here.com", 636) or die("no connection.");
echo "connect successful";
ldap_set_option($conn, LDAP_OPT_PROTOCOL_VERSION, 3);
$ldapbind = ldap_bind($conn, 'user@domain.com', 'password');
echo "bind successfull";
if ($ldapbind) {
        echo "LDAP bind successful";
    } else {
        echo "LDAP bind failed";
	echo ldap_error($conn);
    }

Resulted in this output:

...
ldap_init: trying D:\a\winlib-builder\winlib-builder\install\etc\openldap\ldap.conf
...

But I expected this output instead:

ldap_init: trying c:\openldap\sysconf\ldap.conf

I installed PHP 8.5.6 and encountered issue with self-signed certificate and LDAPs connection. In the previous PHP versions, PHP-LDAP-Module was searching for ldap.conf in folder c:\openldap\sysconf\ on windows system.
Somehow, this default path changed to the cryptic path D:\a\winlib-builder\winlib-builder\install\etc\openldap\ldap.conf
I used the package php-8.5.6-nts-Win32-vs17-x64.zip
Manually setting LDAPCONF works but the default shouldn't have changed to this cryptic path imho.
