Mutual TLS Authentication

By default, servers using TLS provide one-way authentication. The client is certain that the
identity of the server is authentic. When an organizational PKI is used, two-way
authentication may be desired - both client and server should be authenticated using X.509
certificates. This is achieved by installing a client certificate on the managing PC and
loading the root CA's certificate to the device's Trusted Root Certificate Store. The Trusted
Root Certificate file may contain more than one CA certificate combined, using a text
editor.
Since X.509 certificates have an expiration date and time, the device must be configured to
use NTP (see 'Simple Network Time Protocol Support' on page 99) to obtain the current
date and time. Without the correct date and time, client certificates cannot work.
