Error configuring LDAP

Hi, I'm trying to convince my company to adopt ProjeQtor for project management, and I'm running some tests in the tool.
Everythin was running really fine, but when I'm trying to configure LDAP authentication the log always register the same error message:

2018-02-22 10:09:08.256 ***** ERROR ***** [V6.5.5] Ldap not installed on your PHP server. Check php-ldap extension or you should not set $paramLdap_allow_login to "true"

I'm running on Easyphp, I've already remove the coment on php.ini (extension=php_ldap.dll) and I've checked $paramLdap_allow_login = 'true'; and its ok.

I've already tried to update the php_ldap.dll but still no success.
I'm running out of alternatives to verify.... if you people could enlight me I'll appreciate.

I'm sending the info.php, because I've read in other thread someone requesting.

Thanks for any help!
