AAA Authentication and Authorization for Roles

This section describes how to configure AAA Authentication and Authorization for Roles.
Configuration Task List for AAA Authentication and Authorization for Roles
This section contains the following AAA Authentication and Authorization for Roles configuration tasks:
• Configuring AAA Authentication for Roles
• Configuring AAA Authorization for Roles
• Configuring TACACS+ and RADIUS VSA Attributes for RBAC
Configure AAA Authentication for Roles
Authentication services verify the user ID and password combination. Users with defined roles and users with privileges are authenticated
with the same mechanism. There are six methods available for authentication: radius, tacacs+, local, enable, line, and none.
When role-based only AAA authorization is enabled, the enable, line, and none methods are not available. Each of these three methods
allows users to be verified with either a password that is not specific to their user ID or with no password at all. Because of the lack of
security these methods are not available for role only mode. When the system is in role-only mode, users that have only privilege levels are
denied access to the system because they do not have a role. For information about role only mode, see
Authorization.
NOTE: Authentication services only validate the user ID and password combination. To determine which commands are permitted
for users, configure authorization. For information about how to configure authorization for roles, see
Authorization for Roles.
