# USER AUTHENTICATION

This setting enables or disables user authentication and specifies the authentication method.
When the user authentication is enabled, each user of the machine is registered. When a user logs in, the separate authentication settings apply to the user. This function allows greater control of security and cost management than that on previous machines.
Even if user information is not stored on the machine, you can directly enter the user information stored in an LDAP server to log in the machine if necessary. In this case, the authentication information of the "User" being stored as factory default applies to the login user. For more information, see "Users stored as factory default".

- For the procedure for storing users, see "USER LIST".
- For details on login procedures when user authentication is enabled, see "User authentication" of the "OPERATIONS COMMON TO ALL MODES".

User Authentication
When [User Authentication] is enabled, the authentication screen appears before an operation is carried out in any mode except the job status screen*.
Log in as an already registered user.
After logging in, you can move freely through the modes.

*
  The login screen appears when a document filing file is used or when a broadcast transmission is reattempted from the job status screen.

Authentication Method Setting
This selects the authentication method. When using user authentication, be sure to configure this setting first. The items to be configured for users stored after setting the user authentication method vary depending on the selected authentication method.
Authenticate a User by Login Name and Password
Standard authentication method using a login name and password.
Authenticate a User by Login Name, Password and E-mail Address
This authentication also checks the e-mail address, in addition to the login name and password of the user.
Authenticate a User by User Number Only
Use this option for simple authentication if you skip the network authentication.

- The login screen will vary depending on the authentication method that is selected.
  For details, see "User authentication" of the "OPERATIONS COMMON TO ALL MODES".
- When "Authenticate a User by User Number Only" is selected for the authentication method, network authentication cannot be used.

Device Account Mode Setting
A specific user can be registered as an auto login user. When this option is enabled, the registered user can log in the machine automatically.
This function can eliminate each login procedure on the authentication screen and apply the selected user settings (such as network authentication and favourite operations). As an example, this enables uses such as "authentication for one-sided copying only".
Also, you can temporarily log in as a user other than the auto login user, and operate the machine with the privileges of this user. To allow other users to log in temporarily when [Device Account Mode] is enabled, select [Allow Login by Different User].
If you have logged in as the Auto Login user, and if you have failed automatic login due to some reasons or if you do not have the administrator's privileges, you cannot use the general setting modes or Setting mode. In that case, the administrator should tap the [Administrator Password] key on the Setting mode screen and log in again.
To log in as a user other than a fixed user when [Allow Login by Different User] is enabled, tap the [Logout] key to cancel the fixed user login state. When the user authentication screen appears, log in as the desired user again. After you have used the machine, tap the [Logout] key to log out as the current user.
