LDAP problem client in Windows Server

Hello, I'm new in a LDAP installation and I have a problem whyt a client Installation.

For installation I followed these steps:

1 - Uncomment in php.ini the extension = php_ldap.dll
2 - Add the missing dlls to the directory: php_ldap.dll, libsasl.dll, php4ts.dll and libeay32.dll.

Now to make a php-m from the php directory shows me the following error:

PHP Warning: PHP Startup: ldap: Unable to initialize module Module compiled with module API=20001222, debug=0, thread-safety=1 PHP compiled with module API=20060613, debug=0, thread-safety=1
These options need to match

Where is the problem? You know what can be?

Thak you!!!!!!!!!
