LDAP support added for PHP on the new WAMPServer2.2a for Windows?

Hi,

I have installed WAMPServer2.2a for Windows .exe package. When i try to enable LDAP by uncommenting the php_ldap.dll extention in “C:\wamp\bin\apache\Apache2.2.21\bin\php.ini” file, i’m getting an error after restarting apache as,
"PHP Startup: Unable to load dynamic library ‘c:/wamp\bin\php\php5.3.8\ext\php_ldap.dll’ - The specified module could not be found. "

Even though the php_ldap.dll is there in the above path!

Is LDAP enabled in the latest WAMP Server 2.2a package for windows? or am i missing something?

Thanks,
Ramki
