laravel adldap2/adldap2-laravel package

Hi

I am implementing LDAP authentication in laravel app. I am not getting LDAP users when I run this code I am getting an empty collection.

 protected function attemptLogin(Request $request)
    {
       $ldap = new Adldap;
       $data = Adldap::getDefaultProvider()->search()->users()->get();
   
       dd($data);

    }

I got LDAP credential from clients but I am not understanding how to add in .env files.

the credential which I got

User Name: username
 Password: password
 IP:172.16.xx.xx
 Port: 389
 Attributes: CN=user.admin,CN=Users,DC=UATADSRV,DC=COM

my .env file

LDAP_HOSTS=172.16.xx.xx
LDAP_BASE_DN=CN=user.admin,CN=Users,DC=UATADSRV,DC=COM
LDAP_USER_ATTRIBUTE=samaccountname
LDAP_CONNECTION=default
LDAP_USERNAME=username
LDAP_PASSWORD=password

ldap.php

I don't whether it is correct or not. Please help me out how to test LDAP connection using this credential.
