How to Configure TACACS+ Authentication

  • Last updated on

Terminal Access Controller Access-Control System Plus (TACACS+) is an access control network protocol (TCP) for routers, network access servers, and devices. Unlike RADIUS, TACACS+ uses separate authentication and authorization. TACACS+ provides centralized user and group management and offers extended logging options. TACACS+ supports multiple protocols, e.g., IP and  AppleTalk .

Configure TACACS+

To configure TACACS+ for external authentication with the Barracuda NG Firewall,

  1. Open the Authentication Service page (Config > Full Config > Box > Infrastructure Services).
  2. In the left navigation pane, select TACACS+ Authentication.
  3. Click Lock.
  4. Enable TACACS+ as external directory service.
  5. In the TACACS+ IP Address table, add an entry for each TACACS+ server. You can edit the following settings:
    • TAC+ IP Address – IP address of the TACACS+ server.
    • TAC+ ID Port – ID Port information. E.g.: tty10
    • TAC+ Server Port – TCP port of the TACACS+ server.
    • TAC+ Key – DES encryption key.
    • Timeout (s) – Authentication timeout in seconds.
    • TAC+ Login Type – TACACS+ login type (inbound).
  6. Click OK.
  7. If group information is queried from a different authentication scheme, select the scheme from the User Info Helper Scheme list.
  8. Click Send Changes and Activate.
