Issue connecting to LDAP through PHP

Question

My company recently changed domains due to an ownership change and I am having an issue getting my LDAP bind to complete on the new domain.

My connect command creates the resource correctly but when I go to bind I get the error.

"Warning: ldap_bind(): Unable to bind to server: Strong(er) authentication required"

I am not using ldaps. I have confirmed I have the correct domain url for LDAP.

$ad is the resource, $dmun is the username with domain added and the $pw is the password.

$bd = ldap_bind($ad,$dmun,$pw);

It's an intranet site.

Try This code. This code worked for me

$username = 'username';
$password = 'password';
$ldap_host = "domain.com";
$ldap_port = 389;
$base_dn = "DC=domain,DC=com";
$filter = '(sAMAccountName=' . $username . ')';
$connect = ldap_connect($ldap_host, $ldap_port) or exit("Error : Could not connect to LDAP server.");
if ($connect) {
    ldap_set_option($connect, LDAP_OPT_PROTOCOL_VERSION, 3);
    ldap_set_option($connect, LDAP_OPT_REFERRALS, 0);
    if (@$bind = ldap_bind($connect, "$username@domain.com", $password)) {
        echo "Bind Successfull";
    } else {
        echo "Invalid Username / Password";
    }
}
