Server Registration

[LDAP-IC Card Authentication Server Name]

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

[External Authentication Server]

Select the external authentication server used to associate the LDAP-IC card authentication (default: [No Selection]).

When authentication succeeds, user authentication information is registered on the machine to manage users on the machine. This authentication information includes the user name and external authentication server name. The external authentication server name selected here is registered on the machine together with the user name.

[Card Information Registration Settings]

When authentication is performed on the machine using an IC card not registered in the LDAP server, select whether to register the card information in the LDAP server (default: [OFF]).

• [Sequential Server Card Registration]: Specify the server to register card information in. If you select [Primary Server for Card Registration], card information is registered in the server with authentication succeeded among the primary and secondary servers.

• [User Name Attribute]: Specify the attribute to be searched as the user name.

[Card Information Character Type During Search]

Select the search string conversion method to search for the card ID via the LDAP server (default: [Uppercase Letters/ Lowercase Letters]).

When the target card attribute information on the server is unified into upper and lower case letters, in some cases, you can convert the character type of the search string and subsequently reduce the search speed.

• [Uppercase Letters/ Lowercase Letters]: Converts the card ID into upper or lower case letters to carry out a search.

• [Uppercase Letters]: Converts the card ID to uppercase letters to carry out a search.

• [Lowercase Letters]: Converts the card ID to lowercase letters to carry out a search.

[Server Address]

Enter the LDAP server address. Use one of the following formats.

• Example to enter the host name: "host.example.com"

• Example to enter the IP address (IPv4): "192.168.1.1"

• Example to enter the IP address (IPv6): "fe80::220:6bff:fe10:2f16"

[Port No.]

If necessary, change the LDAP server port number (default: [389]).

[Enable SSL]

When using SSL communications, set this option to ON (default: OFF).

• [Port No.(SSL)]: If necessary, change the port number for SSL communication (default: [636]).

[Certificate Verification Level Settings]

To validate the certificate during SSL communication, select items to be verified.

• [Expiration Date]: Confirm whether the certificate is within the validity period (default: ON).

• [CN]: Confirm whether CN (Common Name) of the certificate matches the server address (default: OFF).

• [Key Usage]: Confirm whether the certificate is used according to the intended purpose approved by the certificate issuer (default: OFF).

• [Chain]: Confirm whether there is a problem in the certificate chain (certificate path) (default: OFF). The chain is validated by referencing the external certificates managed on this machine.

• [Expiration Date Confirmation]: Confirm whether the certificate has expired (default: OFF). The expiration date confirmation is performed in the order of OCSP (Online Certificate Status Protocol) service, and CRL (Certificate Revocation List).

[Search Base 1] to [Search Base 3]

Specify the starting point and range to search for a user to be authenticated.

• [Search Base]: Specify the starting point to search for a target (using up to 255 characters).
  Example of entry: "cn=users,dc=example,dc=com"

• [Search Range]: Select a tree search range (default: [Full Tree]).
  [Full Tree]: Makes a search, including the tree structure under the entered starting point.
  [Next hierarchy only]: Searches for only one level directly beneath the entered starting point. In this case, the level at the starting point is not included as a search target.

[Timeout]

If necessary, change the time-out time to limit a communication with the LDAP server (default: [60] sec.).

[General Settings]

Select the authentication method to log in to the LDAP server depending on your environment (default: [Simple]).

• [Login Name]: Enter the login name used for LDAP authentication (using up to 64 characters). In this step, enter the user (name) that belongs to a specific administrator group on the LDAP server.

• [Password]: Enter the password for LDAP authentication (using up to 64 characters).

• [Domain Name]: If [GSS-SPNEGO] is selected for [General Settings], enter the domain name of Active Directory (using up to 64 characters).

[Use Referral]

Select whether to use the referral function (default: [ON]).

[Search Attribute]

When performing LDAP search, enter the search attribute to be automatically added before the user name (using up to 64 characters). The attribute must start with an alphabet character (default: [uid]).

[User Name]

Select how to obtain the user name when logging in to this machine (default: [Use Card ID]). If [ON] is selected in [Card Information Registration Settings], [Acquiring] is selected, and any change cannot be made.

• [Use Card ID]: Select this option when only IC card information is registered on the server. Uses the card ID in the IC card as the user name.

• [Acquiring]: Select this option when user information other than IC card information is registered on the server. Uses the user name obtained from the server. Enter the attribute to be searched as the user name ("uid") at [User Name Attribute].

[Search Directory Service]

If you select [Active Directory], you can limit a search target for authentication to users (default: [Other]). However, when a search target for authentication is limited to users, search target identification processing occurs on the server side, so the authentication time may be delayed. This function is available when the authentication server is set to Active Directory (Windows Server 2008 or later).

[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: [Set Reconnect Interval]). 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.

[Card Information Registration Settings]

When authentication is performed on the machine using an IC card not registered in the LDAP server, select whether to register the card information in the LDAP server.

• [Same as 1st Server]: Select [Enable] when using the same setting as for the primary server. When using a setting different from that of the primary server, select [Disable], then specify the attribute that is to be searched as the user name in [User Name Attribute].

Secondary Server Information

Register the secondary server.

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

To extract the primary server setting and configure the secondary server setting, tap [Same as 1st Server].
