authentication
A user's e-mail address obtained via Windows, LDAP, or Integration Server authentication can be used
as the sender's fixed address ("From") when sending e-mails in the scanner mode or when forwarding
received faxes in order to prevent ID fraud.
If the user authentication method is switched halfway
• A user code account, that has no more than eight digits and is used for User Code
authentication, can be carried over and used as a login user name even after the
authentication method has switched from User Code authentication to Basic authentication,
Windows authentication, LDAP authentication, or Integration Server authentication. In this
case, since the User Code authentication does not have a password, the login password is set
as blank.
• When authentication switches to an external authentication method (Windows authentication,
LDAP authentication, or Integration Server authentication), authentication will not occur,
unless the external authentication device has the carried over user code account previously
registered. However, the user code account will remain in the Address Book of the machine
despite an authentication failure.

Authentication is performed using the machine's address book.
It is necessary to register users in the machine's address book in
advance.
Authentication can be applied to each user.
Authentication is performed using the domain controller of the
Windows server on the same network as the machine.
Authentication can be applied to each user.
Authentication is performed using the LDAP server on the same
network as the machine.
Authentication can be applied to each user.
Authentication is performed using an external authentication server
on the same network as the machine.
This establishes an environment in which authentication is applied
collectively to users of devices (such as MFPs and computers) over
the network.
Authentication can be applied to each user.
To create an external authentication server, software including
Authentication Manager (e.g., Remote Communication Gate S) is
required.
