I found not only "Versions before PHP 4.3.0 additionally require libsasl.dll.".
If you use php-5.3.3-Win32-VC9-x86 or later Versions that
It's require libsasl.dll.
Running under Windows & Apache 2.2.8
PHP file is download from http://windows.php.net/downloads/releases/archives/
When I use php-5.2.x-Win32-VC6-x86 and php-5.3.x-Win32-VC6-x86
1.just uncomment extension=php_ldap.dll in php.ini
2.Restart apache,it's ok
When I use php-5.3.x-Win32-VC9-x86 and php-5.4.x-Win32-VC9-x86
