Enabling LDAP support on Win2k Server

Hi all. I am running PHP on a Windows 2000 Server, and I need to enable LDAP support. So I have viewed the <http://us3.php.net/manual/en/ref.ldap.php> page on how to get LDAP running. However, I have run into a snag. I have copied the two required .dlls (libeay32 & ssleay32) into the system folder. I also put the configuration option 'ldap.max_links = -1' in my php.ini file. Is there anything else I need to add to the .ini file? I tried uncommenting the extension for php_ldap.dll, thinking that that might make it work... but it didn't. Anyone have any suggestions b/c I'm stuck? Thanks, ~Philip
