About general security settings
You can prioritize local, RADIUS, and TACACS+ authentication methods for the system and set the authorization policy and default user for RADIUS and TACACS+ authorization systems in the Administration > Security: General Settings page.
Make sure to put the authentication methods in the order you want authentication to occur. If authorization fails using the first method, the next method is attempted, and so forth, until all the methods have been attempted.
To set TACACS+ authorization levels (admin or read-only) to allow certain members of a group to log in, add these attribute to users on the TACACS+ server:
service = rbt-exec {
local-user-name = "monitor"
}
where you replace monitor with admin for write access.
For details about setting up RADIUS and TACACS+ servers, see the SteelHead Deployment Guide.
