LDAP on a Windows10 client Apache 2.4 and PHP 7.2.12

I'm trying to enable the LDAP extension on my php7 installation. When you start the Apache 2.4 server, you receive the following error message:

php_ldap.dll (the specified module was not found.)

On the net, I've come up with ideas with libsasl.dll, libeay32.dll and ssleay32.dll. In PHP7, only libsasl.dll is included. So I guess PHP has made some changes between PHP5 and PHP7.

How can I run ldap on Windows?
