Sorry - I was referring to "php_ldap.dll", not php_lamp.dll

LDAP support in PHP is not enabled by default. You will need to use the --with-ldap[=DIR] configuration option when compiling PHP to enable LDAP support. DIR is the LDAP base install directory. To enable SASL support, be sure --with-ldap-sasl[=DIR] is used, and that sasl.h exists on the system.
Nota: Note to Win32 Users
Para esta extensão funcionar, existem arquivos DLL que devem estar disponíveis no PATH do sistema Windows. Para saber como fazer isso, veja o FAQ intitulado "Como eu adiciono o meu diretório PHP no PATH no Windows". Embora copiando arquivos DLL da pasta do PHP no diretório system do Windows também funcione (porque o diretório system está por padrão no PATH do sistema), isto não é recomendado. Esta extensão requer que os seguintes arquivos estejam no PATH: libeay32.dll and ssleay32.dll
Versions before PHP 4.3.0 additionally require libsasl.dll.
In order to use Oracle LDAP libraries, proper Oracle environment has to be set.

If you're running on Windows XP with Apache, and you installed PHP 5 from the windows installer rather than the full zipped version - you may not have the php_ldap.dll file.
I had to follow the steps above, making sure PHP was added to my Windows Path, adding the 2 dll files to the system32 directory, also making sure the php.ini extensions directory was set correctly (in my case: C:\Program Files\PHP\ext).
Still was a getting a message about not being able to locate the "php_lamp.dll" file. I finally went back, downloaded the full .zip file of latest PHP version, and that missing dll file is included there - along with many others.
Remember to restart Apache server after you do all this.

with EasyPHP uncomment in php.ini the extension
extension=php_ldap.dll
Restart the server and it works.

Running under IIS, I found php_ldap would not load even though d:\php contained libeay32.dll and ssleay32.dll, and d:\php was in the PATH environment variable.
I finally tracked this down to the position of d:\php in the PATH. If d:\php is near the head of the PATH, everything works fine. If d:\php is near the end of the PATH, apparently it gets ignored by IIS (even though it works fine from the command line, e.g., with php -m). Have no idea why this is.

Running under IIS, I did not find the need to download and compile libraries.
1. Edit PHP.INI (which should be in windows directory)
2. Uncomment the line extension=php_ldap.dll
3. Restart IIS
