[php-src] Issue #22130: Default-Search path for ldap.conf changed to D:\a\winlib-builder\winlib-builder\install\etc\openldap\ldap.conf

Issue: https://github.com/php/php-src/issues/22130 Author: HoffmannTom ### Description The following code: ```php <?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. ### PHP Version ```plain PHP 8.5.6 (cli) (built: May 6 2026 09:31:48) (NTS Visual C++ 2022 x64) Copyright (c) The PHP Group Built by The PHP Group Zend Engine v4.5.6, Copyright (c) Zend Technologies with Zend OPcache v8.5.6, Copyright (c), by Zend Technologies ``` ### Operating System Windows 2016
