Under XAMPP on Windows the ldap.conf must be either in the root of the system (c:\ldap.conf, PHP 5.3.3 if I remember correctly) or in C:\openldap\sysconf\ depending on the PHP version. It seems the path is not configurable because hardcoded in the Windows PHP DLLs. See the comments at http://se2.php.net/manual/en/ref.ldap.php
