unable to login in laravel using LDAP package Adldap2-Laravel

Hi

I am using the Adldap2-Laravel package for authentication. I am testing using the LDAP test forum. I followed this tutorial https://jotaelesalinas.github.io/laravel-simple-ldap-auth/ But I am unable to login. I am not getting any errors. In the below code always else block is executing.

I think I have made mistake in configuration Please help me

Thank You

login controller

  protected function attemptLogin(Request $request)
    {
        
        $credentials = $request->only($this->username(), 'password');
        $username = $credentials[$this->username()];
        $password = $credentials['password'];

        $user_format = env('LDAP_USER_FORMAT', 'cn=%s,'.env('LDAP_BASE_DN', ''));
        $userdn = sprintf($user_format, $username);


        if(Adldap::auth()->attempt($userdn, $password, $bindAsUser = true)) {

            dd('working'); 
        }
        else
        {
            dd('not working');

        }  
    }
