Client Setting

[SMB TX Setting]

When using the SMB TX function, set this option to ON (default: ON).

[SMB Authentication Setting]

Select an authentication method for SMB transmission according to your environment (default: [NTLM v1/v2]).

• [NTLM v1]: Performs the NTLM v1 authentication. This option is available in the NT domain environment.

• [NTLM v2]: Performs NTLM v2 authentication. This option is available in the NT domain environment.

• [NTLM v1/v2]: Performs NTLM v1 authentication when NTLM v2 authentication fails. This option is available in the NT domain environment or Mac OS environment.

• [Kerberos]: Performs Kerberos authentication. This option is available in the Active Directory domain environment.

[Authentication Setting if Kerberos Fails]

If [Kerberos] is selected in [SMB Authentication Setting], select whether to perform NTLM authentication when Kerberos authentication has failed (default: [Disable NTLM]).

• [Enable NTLM v1/v2]: NTLM v2 authentication is performed when Kerberos authentication fails, and NTLM v1 authentication is performed when NTLM v2 authentication fails. This option is available when both the Active Directory and NT domains are specified.

• [Disable NTLM]: Assumes that authentication fails when Kerberos authentication has failed.

[Single Sign-On Setting]

Configure the single sign-on function for SMB transmission.

By using the user authentication information (login name and password) of this machine as SMB destination authentication information (user ID and password), you can reduce the number of steps required to specify SMB destination authentication information, enabling you to configure a single sign-on environment for SMB transmission.

• [Default Domain Name]: When a server other than Active Directory is used for external server authentication or external server authentication is not used, specify the name of the domain to which the destination host belongs at SMB transmission (using up to 64 characters).
  When Active Directory is used for external server authentication, the value specified in this step is ignored, and the domain name of the login destination for external server authentication is used instead.
  If [Kerberos] is selected in [SMB Authentication Setting], entry is required.

• [SMB User Credential Setting]: When using the user authentication information (login name and password) of this machine as SMB destination authentication information (user ID and password), set this option to ON (default: OFF).

• [Edit SMB User Credentials]: This option is available when [SMB User Credential Setting] is set to ON (default: OFF).
  Setting to OFF (Restrict) registers SMB destinations, excluding the user ID and password specified at login. However, using Web Connection, an SMB destination is registered, including the user ID and password.
  Setting to ON (Allow) enables you to select whether to register SMB destinations, including the user ID and password. Selecting [Reg. excl. ID and Password] automatically adds the user ID and password at SMB transmission.

[User Authentication(NTLM)]

When performing user authentication via the NTLM server, set this option to ON (default: ON).

[DFS Setting]

When using DFS, set this option to ON (default: ON).

[SMB security Signature Setting]

Select whether to enable the SMB signature of this machine to suit your environment (default: [When requested]).

• [Disable]: Disables the SMB signature of this machine.

• [When requested]: Enables the SMB signature of this machine (client) only when the SMB signature is requested from the server side. If the SMB signature is not requested from the server side, operations are performed while the SMB signature of this machine (client) remains disabled, and a connection is possible even when the SMB signature on the server side is disabled.

• [Required]: Enables the SMB signature of this machine. To establish a connection, the SMB signature is also required in the server side. If the SMB signature in the server side is disabled, it will not be possible to make a connection.
