TACACS+

TACACS+ (Terminal Access Controller Access Control System) provides access control for networked devices via one or more centralized servers. Similar to RADIUS, this protocol simplifies authentication by making use of a single database that can be shared by many clients on a large network. TACACS+ is based on the TACACS protocol described in RFC1492. TACACS+ uses TCP to ensure reliable delivery and a shared key configured on the client and daemon server to encrypt all messages.

After you configure TACACS+ as the authentication method for user login, the NAS (Network Access Server) prompts for the user login credentials and requests services from the DWS-3000 TACACS+ client. The client then uses the configured list of servers for authentication, and provides results back to the NAS. You can configure the TACACS+ server list with one or more hosts defined via their network IP address. You can also assign each a priority to determine the order in which the TACACS+ client will contact them. TACACS+ contacts the server when a connection attempt fails or times out for a higher priority server.

You can configure each server host with a specific connection type, port, timeout, and shared key, or you can use global configuration for the key and timeout.

Like RADIUS, the TACACS+ server can do the authentication itself, or redirect the request to another back-end device. All sensitive information is encrypted and the shared secret is never passed over the network - it is used only to encrypt the data.

TACACS+ Configuration Example

This example configures two TACACS+ servers at 10.10.10.10 and 11.11.11.11. Each server has a unique shared secret key. The server at 10.10.10.10 has a default priority of 0, the highest priority, while the other server has a priority of 2. A new authentication list called tacacsList is created which uses TACACS+ to authenticate, and uses local authentication as a backup method. This authentication list is then associated with the default login.
