[External Server Name]

Enter the name of the authentication server (using up to 32 single-byte characters).

[External Server Type]

Select [NTLM v1] or [NTLM v2].

[NTLM]

Register server information when NTLM is used as the authentication server.

• [Default Domain Name]: Enter the default domain name of your authentication server (using up to 64 single-byte characters).

[2nd Server Setting]

When using the secondary server, set this option to ON (default: OFF).

[Round Robin function]

When using the round-robin function, set this option to ON (default: OFF).

If you select round-robin function, you can alternately connect the primary and secondary servers to distribute the server load.

[Reconnection Settings]

Configure a setting to connect to the secondary server when the machine cannot be connected to the primary server (default: [Reconnect for every login]). When the round-robin function is enabled, this setting can also be used to connect to the primary server when the machine cannot be connected to the secondary server.

• [Reconnect for every login]: Connects to the primary server each time authentication is carried out on this machine. If the primary server is shutting down, this machine is connected to the secondary server.

• [Set Reconnect Interval]: Connects to the secondary server when the primary server is shutting down at the time the machine is being authenticated. After this, this machine is connected to the secondary server when machine authentication is occurring until the time specified in [Reconnection Time] lapses. After the time specified in [Reconnection Time] has lapsed, this machine is reconnected to the primary server when machine authentication is occurring.

[External Server Type]

Select the type of the authentication server and set required information.

For details, refer to the registration contents of the primary server.

[User Authentication]

When performing authentication using an external authentication server, select [ON (External Server)] or [ON (MFP + External Server)].

If you want to configure setting so that you can log in to this machine using its authentication function in consideration of an occurrence of some sort of problem on the external authentication server, select [ON (MFP + External Server)].

[Default Authentication Method]

If [User Authentication] is set to [ON (MFP + External Server)], select the preferential authentication method (default: [ON (External Server)]).

[When Number of Jobs Reach Maximum]

Sets the maximum number of sheets that each user can print. Here, select an operation if the number of sheets exceeds the maximum number of sheets that can be printed (default: [Skip Job]).

• [Skip Job]: Stops the job currently running, and starts printing the next job.

• [Stop Job]: Stops all jobs.

• [Delete Job]: Deletes the active job.

[External Authentication server setting]

Set server authentication operations.

• [Temporarily Save Authentication Information]: To temporarily save authentication information in the main unit against a case where an external authentication server shuts down, set this option to ON (default: OFF).

• [Reconnection Settings]: Specify the timing to reconnect to the authentication server (default: [Set Reconnect Interval]).
  [Reconnect for every login]: Connects to the authentication server at the time authentication is carried out on this machine. If the authentication server is in the shutdown state at the time authentication is carried out on this machine, first confirm that the authentication server is down, and use the temporarily saved authentication information to log in to this machine.
  [Set Reconnect Interval]: Connect to the authentication server at the time specified in [Reconnection Time], and check the status of the authentication server. If the authentication server is in the shutdown state, use the authentication information temporarily saved in the main unit to log in.

• [Expiration Date Settings]: When specifying the validity period to the temporarily saved authentication information, set this option to ON (default: OFF). Also, enter the expiration date.

• [Overwrite User Info]: When the external server authentication is used, authenticated user information is also managed on this machine. If the number of users who have executed the external server authentication reaches the maximum number of users this machine can manage, authentication of any new users will not be permitted. Select whether to allow the user to overwrite registered user information for that case (default: [Restrict]). If you select [Allow], the oldest authenticated user information is erased and the new user is registered.
