Add AAA Servers to the Node’s List

If you enable an external authentication option (RADIUS, TACACS+, or LDAP) with the AAA, you must also perform some additional configuration tasks, both within the GigaVUE node and the external server itself:

 

1 Steps to Use the Node with an External Authentication Server

RADIUS Server

Admin users use the RADIUS page to specify the RADIUS servers to be used for authentication. You can specify multiple RADIUS servers. Servers are used as fallbacks in the same order they are specified—if the first server is unreachable, the second is tried, and so on, until all named servers have been used. If a server is reachable and authentication fails, the authentication process terminates.

Use the following buttons to manage the RADIUS server.

Add

Use to add a RADIUS server. Refer to Add a RADIUS Server section for details.

Actions

Use to perform the following tasks:

Edit: Use to edit the RADIUS server configuration.

Delete: Use to delete the selected RADIUS server. Refer to Delete a RADIUS Server for details.

Default Settings

Use to apply the default settings for RADIUS

Export

Use to export the selected RADIUS servers or all RADIUS servers in CSV or XLSX format.

Add a RADIUS Server

To Add a RADIUS server, do the following:

1.   Select Settings > Authentication > RADIUS.
2. Click Add.
3. Enter the RADIUS information on the Add RADIUS Server page. For an example, refer to 2.
a. You can enter either an IPv4 or IPv6 address for the Server IP/DNS Name. The same IP address can be used for more than one RADIUS server if the Auth Port values are different.
b. Specify the shared secret key to be used for encryption of authentication packets sent between the GigaVUE HC Series node and this specific RADIUS server.
4. Click Apply to save the configuration.

2 Adding a Radius Server

Delete a RADIUS Server

To delete a RADIUS server, do the following:

1.   Select Settings > Authentication > RADIUS.
2. Select the RADIUS server to delete.
3. Click Actions button and select Delete.

Add a TACACS+ Server

Admin users use the TACACS+ page to specify the TACACS+ servers to be used for authentication. You can specify multiple TACACS+ servers. Servers are used as fallbacks in the same order they are specified – if the first server is unreachable, the second is tried, and so on, until all named servers have been used. If a server is reachable and authentication fails, the authentication process terminates.

To add a TACACS server, do the following:

1.   Select Settings > Authentication > TACACS+.
2. Click Add.
3. Enter the TACACS information on the ADD TACACS Server page. For an example, refer to 3
4. Click Save.

3 Adding a TACACS Server

Delete a TACACS+ Server

To delete a TACACS+ server, do the following:

1.   Select Settings > Authentication > TACACS+.
2. Select the TACACS+ server to delete.
3. Click Delete.

Configure an IPv6 Address

To configure an IPv6 address for a TACACS+ server, enter the IPv6 address in the Server IP filed on the Add TACACS Server page (select Settings > Authentication > TACACS > Add.)

Note:  To use IPv6 addresses, you must use the CLI to enable IPv6 through the configuration jump-start wizard. For more information, refer to the GigaVUE-OS CLI Reference Guide.

Add an LDAP Server

Admin users use the LDAP page to specify the LDAP servers to be used for authentication. You can specify multiple LDAP servers. Servers are used as fallbacks in the same order they are specified—if the first server is unreachable, the second is tried, and so on, until all named servers have been used. If a server is reachable and authentication fails, the authentication process terminates.

To add an LDAP Server, do the following:

1.   Select Settings > Authentication > LDAP.
2. Click Add.
3. Enter the IP address of the LDAP server in the Server IP field.
4. Enter the priority.
5. Click Save.

For Common Criteria, specify SHA password hashing when configuring the remote LDAP server. For details on Common Criteria, refer to Common Criteria.

Set the LDAP Server Default Settings

After adding an LDAP Server, do the following to specify the default settings:

1.   Select Settings > Authentication > LDAP.
2. Select the LDAP Server, and then click Default Settings.
3. Enter or select the settings for the LDAP server on the Edit LDAP Server Default Settings page, and then click Save. The settings are described in Table 4: LDAP Default Settings

Table 4: LDAP Default Settings

Default Setting

Description

User Base DN

Identifies the base distinguished name (location) of the user information in the schema of LDAP server. Specify this by identifying the organizational unit (ou) in the base DN. Provide the value as a string with no spaces. For example:

ou=People,dc=mycompany,dc=com

This is a global setting. It cannot be configured on a per-host basis.

User Search Scope

Specifies the search scope for the user under the base distinguished name (dn):

● subtree—Searches the base dn and all of its children. This is the default.
● one-level—Searches only the immediate children of the base dn.

This is a global setting. It cannot be configured on a per-host basis.

Login UID

Specifies the name of the LDAP attribute containing the login name. You can select

● uid (for User ID)
● sAMAccountName
● custom attribute and provide a string for the custom attribute name

This is a global setting. It cannot be configured on a per-host basis.

Bind Password

Provides the credentials to be used for binding with the LDAP server. If Bind DN is undefined for anonymous login (the default), Bind Password should also be undefined.

This is a global setting. It cannot be configured on a per-host basis.

Group Base DN

Specifies that membership in the named Group Base DN is required for successful login to the GigaVUE HC Series node.

By default, the Group Base DN is left empty—group membership is not required for login to the system. If you do specify a Group Base DN, the attribute specified by Group Login Attr must contain the user’s distinguished name as one of the values in the LDAP server or the user will not be logged in.

This is a global setting. It cannot be configured on a per-host basis.

Bind DN

Specifies the distinguished name (dn) on the LDAP server with which to bind. By default, this is left empty for anonymous login.

This is a global setting. It cannot be configured on a per-host basis.

Group Login Attr

Specifies the name of the attribute to check for group membership. If you specify a value for Base Group DN, the attribute you name here will be checked to see whether it contains the user’s distinguished name as one of the values in the LDAP server. You ca select on of the following:

■   custom attribute
■   member
■   uniqueMember

This is a global setting. It cannot be configured on a per-host basis.

LDAP Version

Specifies the version of LDAP to use. The default is version 3, which is the current standard. Some older servers still use version 2.

This is a global setting. It cannot be configured on a per-host basis.

Port

Specifies the port number on which the LDAP server is running. If you do not specify a port, the default LDAP authentication port number of 389 is used.

This is a global setting. It cannot be configured on a per-host basis.

Timeout

Specifies how long the GigaVUE HC Series node should wait for a response from an LDAP server to a bind request before declaring a timeout failure.

The valid range is 0-60 seconds. The default is 5 seconds.

Extra Roles

When Yes is selected, enables the GigaVUE HC Series node to accept user roles assigned in the LDAP server. The default is No.

SSL Mode

Enables SSL or TLS to secure communications with LDAP servers as follows:

● none—Does not use SSL or TLS to secure LDAP.
● ssl—Secures LDAP using SSL over the SSL port.
● tls—Secures LDAP using TLS over the default server port.

Note:  SSL and TLS modes use TLS 1.2 for negotiation with the LDAP server and the default ports.

SSL Port

Configures LDAP SSL port number.

SSL Cert Check

Enables LDAP SSL/TLS certificate verification. Use Off to disable.

SSL ca-list

Configures LDAP to use a supplemental CA list. Set to default Ca list to use the CA list configured with the Enhanced Cryptography (refer to Configure Enhanced Cryptography Mode). Set to None if you do not want to use a supplemental list.

Delete an LDAP Server

To delete an LDP Server, do the following:

1.   Select Settings > Authentication > LDAP.
2. Select the LDAP server to delete.
3. Click Delete.

Configure an IPv6 Address

To configure an IPv6 address for a LDAP server, enter the IPv6 address in the Server IP filed on the Add LDAP Server page (select Settings > Authentication > LDAP > Add.)

Note:  To use IPv6 addresses, you must use the CLI to enable IPv6 through the configuration jump-start wizard. For more information, refer to the GigaVUE-OS CLI Reference Guide.
