User authentication

Terminal Access Controller Access-Control System Plus

Your AnywhereUSB Plus device supports Terminal Access Controller Access-Control System Plus

(TACACS+), a networking protocol that provides centralized authentication and authorization

management for users who connect to the device. With TACACS+ support, the AnywhereUSB Plus

device acts as a TACACS+ client, which sends user credentials and connection parameters to a

TACACS+ server over TCP. The TACACS+ server then authenticates the TACACS+ client requests and

sends back a response message to the device.

When you are using TACACS+ authentication, you can have both local users and TACACS+ users able

to log in to the device. To use TACACS+ authentication, you must set up a TACACS+ server that is

accessible by the AnywhereUSB Plus device prior to configuration. The process of setting up a

TACACS+ server varies by the server environment.

This section contains the following topics:
