Configuring authorization methods for an ISP domain
In AAA, authorization is a separate process at the same level as authentication and accounting. Its
responsibility is to send authorization requests to the specified authorization servers and to send
authorization information to users after successful authorization. Authorization method configuration
is optional in AAA configuration.
AAA supports the following authorization methods:
• No authorization (none)—The NAS performs no authorization exchange. After passing
authentication, non-login users can access the network, FTP users can access the root
directory of the NAS, and other login users have Level 0 (visiting) access.
• Local authorization (local)—The NAS performs authorization according to the user attributes
configured for users.
• Remote authorization (scheme)—The NAS cooperates with a RADIUS or HWTACACS
server to authorize users. RADIUS authorization is bound with RADIUS authentication.
RADIUS authorization can work only after RADIUS authentication is successful, and the
authorization information is carried in the Access-Accept message. HWTACACS authorization
is separate from HWTACACS authentication, and the authorization information is carried in the
authorization response after successful authentication. You can configure local authorization or
no authorization as the backup method. The backup method will be used when the remote
server is not available.
Configuration prerequisites
Before configuring authorization methods, complete the following tasks:
1. For HWTACACS authorization, configure the HWTACACS scheme to be referenced first. For
RADIUS authorization, the RADIUS authorization scheme must be the same as the RADIUS
authentication scheme. Otherwise, it does not take effect.
2. Determine the access type or service type to be configured. With AAA, you can configure an
authorization scheme for each access type and service type to limit the authorization protocols
that can be used for access.
3. Determine whether to configure an authorization method for all access types or service types.
Configuration guidelines
When configuring authorization methods, follow these guidelines:
• To configure RADIUS authorization, you must also configure RADIUS authentication, and
reference the same RADIUS scheme for RADIUS authentication and authorization. If the
RADIUS authorization configuration is invalid or RADIUS authorization fails, the RADIUS
authentication also fails. If RADIUS authorization fails, the server sends an error message to
the NAS, indicating that the server itself is not responding.
• You can configure a default authorization method for an ISP domain. This method will be used
for all users who support the authentication method and have no specific authorization method
configured.
• You can configure local authorization (local) or no authorization (none) as the backup for
remote authorization that is used when the remote authorization server is unavailable.
• Local authorization (local) and no authorization (none) cannot have a backup method.
