How to use LDAP connector to get user's name from LDAP server?

Hello

I trying to get the user's name from the LDAP server instead of using the ACME for the validate task.

But when I add LDAP connector in the pool. Nothing happened in the validate task. Before I added its still works but with the ACME user's name (Walter Bates).

So I want to know how do I get the user's name from my LDAP server to connect with the task.

Ps. Currently, I am using Bonitasoft Studio Community 7.10.0

Pps. I am still new please don't yell at me.
