Group authorization on RADIUS
Group information retrieval from a RADIUS authentication server adds another layer of security
by adding a network-based authorization. It retrieves the group information from the
authentication server and performs an authorization through the console server.

To configure a TACACS+ authentication server:

console server or any of its ports are configured to use TACACS+ authentication method or any
of its variations (Local/TACACS+, TACACS+/Local or TACACS+/DownLocal).
1. Go to Security - Authentication - TACACS+ in Expert mode. The TACACS+ form displays.
2. Fill in the form according to your local TACACS+ server configuration.
3. To apply Authorization in addition to authentication to the box and ports, select the
Enable Raccess Authorization checkbox.
By default, Raccess Authorization is disabled and no additional authorization is
implemented. When Raccess Authorization is enabled, the authorization level of users
trying to access the console server or its ports using TACACS+ authentication is
checked. Users with administrator privileges have administrative access and users with
regular user privileges have regular user access.
4. To specify a time-out period in seconds for each authentication attempt, type a number in
the Timeout field.
If the authentication server does not respond to the client’s login attempt before the
specified time period, the login attempt is cancelled. The user may retry depending on
the number specified in the Retries field on this form.
