Verifying Users to Operate the Machine (User Authentication)

There are four types of user authentication methods including Basic authentication that limits use of the machine and methods that use an authentication server in the network. Select a method depending on the usage condition or the number of users. You cannot use more than one authentication method at the same time.

User Authentication Method	Explanation
User Code authentication	Authentication is performed using an up to eight-digit user code registered in the Address Book of the machine. When specifying User Code authentication, the machine prompts you to enter the user code to use the machine. Multiple users can use the same user code. You can activate User Code authentication without activating Administrator Authentication.
Basic authentication	Authentication is performed using the login user name and login password registered in the Address Book on the machine. When specifying Basic authentication, the machine prompts you to enter the login information to use the machine.
Windows authentication	Authentication is performed using the account registered in the Active Directory of the Windows server. When specifying Windows authentication, the machine prompts you to enter the login information to use the machine.
LDAP authentication	Authentication is performed using the user information registered in the LDAP server. When specifying LDAP authentication, the machine prompts you to enter the login information to use the machine.

• In Windows or LDAP authentication, the machine can authenticate you without registering your user information in the machine's Address Book manually, as the user information in the server is registered in the machine automatically.

• In Windows or LDAP authentication, you can manage user information centrally in the server. You can also always use the address provided by the server as the sender (From) of e-mails sent from the machine. These features are useful to avoid data leakage by erroneous input of information or spoofing by an unauthorized user.

• When switching the authentication method from User Code authentication to another method, the user code will be used as the login user name. In this case, the login password is not specified. To avoid unauthorized use, delete unnecessary user information and set up a password for the continuing users.

Specify the functions to restrict with User Code authentication.

1. Log in to the machine as the machine administrator on the control panel.

2. On the Home screen, press [Settings].
   

3. Press [System Settings].

   

4. Press [Settings for Administrator] [Authentication/Charge] [Administrator Authentication/User Authentication/App Auth.] [User Authentication Management].

5. Select [User Code Authentication] from the list next to User Authentication Management.
   

6. Under Functions to Restrict, select the functions to restrict against use.

   • Specify whether to perform User Code authentication for each function. For Copier Function and Printer Function, you can specify to perform User Code authentication for all Copier or Printer functions, or for the color print mode only.
   • When registering the user code of the printer driver automatically, select [PC Control] for Printer Function. Specify the user code registered in the Address Book to the printer driver.

   • When [PC Control] is selected, the user code specified in the printer driver is registered in the Address Book automatically and is excluded from the print volume use limitation. To limit the print volume use, select other than [PC Control] for Printer Function.

2. On the Home screen, press [Settings].
   

3. Press [System Settings].

   

4. Press [Settings for Administrator] [Authentication/Charge] [Administrator Authentication/User Authentication/App Auth.] [User Authentication Management].

5. Select [Basic Authentication] from the list next to User Authentication Management.
   

6. Under Available Functions, select the functions available to the user.

   • Specify the functions available to the user for each function. For Copier Function and Printer Function, you can specify that the user can use all Copier or Printer functions, or the black-and-white print mode only.

   • For Printer Job Authentication, specify the security level for print jobs using the printer driver.

2. On the Home screen, press [Settings].
   

3. Press [System Settings].

   

4. Press [Settings for Administrator] [Authentication/Charge] [Administrator Authentication/User Authentication/App Auth.] [User Authentication Management].

5. Select [Windows Authentication] from the list next to User Authentication Management.
   

6. Register the server for authentication and specify the usable functions.
   

   • Kerberos Authentication: To enable Kerberos authentication, select [On].

   • Domain Name: To disable Kerberos authentication, enter the domain name to authenticate.

   • Realm Name: To enable Kerberos authentication, select the realm name to authenticate.

   • Use Secure Connection (SSL): To encrypt communication signals, select [On].

   • Printer Job Authentication: Specify the security level for print jobs using the printer driver.

   • Group: If global groups have been registered, you can specify usable functions for each global group. Press [* Not Registered], and then [Register/Change]. Enter the same name of the group as the one registered in the server to specify the available functions.
     Users who are registered in multiple groups can use all functions available to those groups.
     A user who is not registered in any group can use the authority specified in [* Default Group]. By default, all functions are available to the Default Group members.

     Under Available Functions, specify the functions available to each group. For Copier Function and Printer Function, you can specify whether the user can use all Copier or Printer functions, or the black-and-white print mode only.

Register the LDAP server information required for authentication with the LDAP server.

1. Log in to the machine as the machine administrator on the control panel.

2. On the Home screen, press [Settings].
   

3. Press [System Settings].

   

4. Press [Settings for Administrator] [Authentication/Charge] [Administrator Authentication/User Authentication/App Auth.] [User Authentication Management].

5. Select [LDAP Authentication] from the list next to User Authentication Management.
   

6. Select the server for authentication and specify the available functions.

   • LDAP Servers: Select the LDAP server to authenticate.

   • Login Name Attribute: Use this as a search criterion to obtain user information. Create a search filter based on the login name attribute, select a user, and then retrieve the user information from the LDAP server to transfer to the machine's Address Book.
     When separating multiple login attributes with a comma (,), the search will return hits by entering a login name for either or both attributes.
     Also, by entering two login names separated by an equal sign (=) (for example: cn=abcde, uid=xyz), the search will return hits only for a match of the attributes of both login names. This search function can be applied when "Cleartext Authentication" is selected as the LDAP authentication method.

   • Unique Attribute: Specify this to match the user information in the LDAP server with that in the machine. A user whose unique attribute registered in the LDAP server matches that of a user registered in the machine is treated as the same user in the machine. Specify the attribute that is used for unique information in the server as the Unique Attribute. You can enter "cn" or "employeeNumber" to use as "serialNumber" or "uid" as long as it is unique.

   • Available Functions: Specify the functions available to the user for each function. For Copier Function and Printer Function, you can specify whether the user can use all Copier or Printer functions, or the black-and-white print mode only. For Printer Job Authentication, specify the security level for print jobs using the printer driver.
