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 NTLMv1 authentication when NTLMv2 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]: NTLMv2 authentication is performed when Kerberos authentication fails, and NTLMv1 authentication is performed when NTLMv2 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 (host name and password), you can avoid the problem of having to specify SMB destination authentication information, allowing construction of a single sign-on environment for SMB transmission.

• [Default Domain Name]: Enter the default domain name to be added to the host name of the destination at SMB transmission (using up to 64 characters). The default domain name cannot be prefixed by an asterisk (*).
  If the domain name of the destination is not specified by the user when sending data using SMB, the domain name specified here is added. This item is not required when Active Directory is used as an authentication server.

• [SMB User Credential Setting]: When using the user authentication information (login name and password) of this machine as SMB destination authentication information (host name 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.
