TACACS+ appliance

Terminal Access Controller Access-Control System Plus (TACACS+) is a protocol developed by Cisco and released as an open standard beginning in 1993. Although derived from TACACS, TACACS+ is a separate protocol that handles authentication, authorization, and accounting (AAA) services.

The tac_plus server is a major rewrite of the original Cisco source code.

For more information see, a reference manual for the configuration file is available at .

An easier TACACS+ configuration can be done with do_auth, see .

The appliance includes tac_passwd, tac_adduser and tac_deluser to manage the password file /etc/tacacs+/passwd.
