It is using NT Authentication. Pulls information from the networks LDAP configuration file, and authenticates against this file. This also locks the FROM field of the Digitally Sent emails. This will make it so that users cannot spoof emails from the 4100MFP. Without this, users can send files/emails with ANY email and name as the sender.
