Adding and Deleting Users from a Role To create a user name that is authenticated based on a user role, use the username name password encryption-type password role role-name command in CONFIGURATION mode. Example The following example creates a user name that is authenticated based on a user role. Dell (conf) #username john password 0 password role secadmin The following example deletes a user role. NOTE: If you already have a user ID that exists with a privilege level, you can add the user role to username that has a privilege Dell (conf) #no username john The following example adds a user, to the secadmin user role. Dell (conf)#username john role secadmin password 0 password 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 Configuring Role-based Only AAA 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 Configure AAA Authorization for Roles. To configure AAA authentication, use the aaa authentication command in CONFIGURATION mode. aaa authentication login {method-list-name | default} method [... method4] Configure AAA Authorization for Roles Authorization services determine if the user has permission to use a command in the CLI. Users with only privilege levels can use commands in privilege-or-role mode (the default) provided their privilege level is the same or greater than the privilege Security 819
