Managing Authentication Servers

On the Users & Objects view > User Management section > Authentication Servers page you can define and view different authentication servers where users can define both an external user database and the authentication method for users in that database.

You can configure these types of authentication:

  • RADIUS server - Define the details of a primary and secondary RADIUS server. The Quantum Spark Appliance can connect to these servers and recognize users defined in them and authenticated by them.

  • TACACS+ server - TACACS+ is an access control mechanism that enables user authentication and authorization of users by a separate server on the network.

Configuring RADIUS Servers

RADIUS servers can be used for:

  • Defining a database of users with remote access privileges. Such users are both defined and authenticated by the RADIUS server.

  • Defining administrators. See the Users & Objects > User Management section > Administrators page.

  1. Click the Users & Objects view > Users Management section > Authentication Servers page.

  2. In the section RADIUS Servers, click Configure.

  3. In the Primary tab, enter this information:

    • IP address - The IP address of the RADIUS server.

    • Port - The port number through which the RADIUS server communicates with clients. The default is 1812.

    • Shared secret - The secret (pre-shared information used for message "encryption") between the RADIUS server and the Quantum SparkAppliance.

      Select Show to see the shared secret.

      Note - You cannot use these characters in a password or shared secret: { } [ ] ` ~ | ‘ " \ (maximum number of characters: 255)

    • Timeout (seconds) - A timeout value in seconds for communication with the RADIUS server. The timeout default is 3 seconds.

    Note - Click Clear if you want to remove information you entered in IP address and Shared secret.

  4. On the Secondary tab, repeat Step 2 for a Secondary RADIUS server if applicable.

  5. Click Apply

    The primary and secondary servers (if defined) are added to the RADIUS section on the page.

  1. Click the Users & Objects view > Users Management section > Authentication Servers page.

    • Port - The port number through which the TACACS+ server communicates with clients. The default is 49.

    • Shared secret - The secret (pre-shared information used for message "encryption") between the TACACS+ server and the Quantum Spark Appliance.

      Select Show to see the shared secret.

      Note - You cannot use these characters in a password or shared secret: { } [ ] ` ~ | ‘ " \ (maximum number of characters: 255)

    • Timeout (seconds) - A timeout value in seconds for communication with the TACACS+ server. The timeout default is 3 seconds.

Configuring Active Directory Servers

  1. Click the Users & Objects view > Users Management section > Authentication Servers page.

  2. In the section Active Directory section, click New.

      Note - With this option, you can synchronize the user database known to the appliance in all locations that this user database can be viewed.

      For example:

      • The Users & Objects view > User Management section > Users page.

      • The Access Policy > view > Firewall section > Policy page > Source picker.

        You cannot select a user from the Active Directory, only an Active Directory user group.

        You can select a local user.

  4. Click Apply

By default, users defined in the Active Directory are not given remote access permissions. Instead, in the VPN > Remote Access section > Remote Access Users page all users defined locally or in Active Directories can be selected to be granted remote access permissions per user.

  1. Click the Users & Objects view > Users Management section > Authentication Servers page.

  2. In the section Active Directory section, click the link in the sentence Remote access permissions for Active Directory users are set in.
