We saw earlier how to install TACACS+ on Kali Linux. This post describes the configuration of authentication on Kali Linux.
Define the shared secret used to communicate between the AAA client and the TACACS+ server:
Rtr-1(config)#tacacs-server host 192.168.1.250 key Blabla
Rtr-1(config)#aaa authentication login default group tacacs+ local
Define a group
Define a user as part of the group.
Rtr-1#deb tacacs authentication TACACS+ authentication debugging is on
Configuring authorization with the tacacs+ Debian deamon is a pain in the ass. I will step away from it and play with either ACS or ISE.
