Here is how to tell if an Active Directory user account expired:

define('LDAP_OPT_DIAGNOSTIC_MESSAGE', 0x0032);

ldap_set_option($conn, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($conn, LDAP_OPT_REFERRALS, 0);

$bind = ldap_bind($conn, $user, $pass);

ldap_get_option($conn, LDAP_OPT_DIAGNOSTIC_MESSAGE, $extended_error);

if (!empty($extended_error))
{
    $errno = explode(',', $extended_error)[2];
    $errno = explode(' ', $errno)[2];
    $errno = intval($errno);

    if ($errno == 532)
        $err = 'Unable to login: Password expired.';
}
