Answer 2

Data save will not happen by itself you need to set data into attribute. If its part of customer Interface For example

$attribute = $customer->getCustomAttribute('client_dn');
if ($attribute)
{
    $customer->setValue("hi");
}

if you are saving using customer object
$customer->setData('client_dn', 'Hi');
