Configuring RADIUS Server Authentication with VSA
In this scenario, an external RADIUS server authenticates management users and returns to the controller the
Dell vendor-specific attribute (VSA) called Dell-Admin-Role that contains the name of the management role for
the user. The authenticated user is placed into the management role specified by the VSA.
The controller configuration is identical to the
Configuring RADIUS Server Username and Password
Authentication on page 862. The only difference is the configuration of the VSA on the RADIUS server. Ensure
that the value of the VSA returned by the RADIUS server is one of the predefined management roles.
Otherwise, the user will have no access to the controller.
Configuring RADIUS Server Authentication with Server Derivation Rule
Dell controllers do not make use of any returned attributes from a TACACS+ server.
A RADIUS server can return to the controller a standard RADIUS attribute that contains one of the following
values:
l The name of the management role for the user
l A value from which a management role can be derived
For either situation, configure a server-derivation rule for the server group.
In the following example, the RADIUS server returns the attribute Class to the controller. The value of the
attribute can be either “root” or “network-operations depending upon the user; the returned value is the role
granted to the user.
Ensure that the value of the attribute returned by the RADIUS server is one of the predefined management roles.
Otherwise, the management user will not be granted access to the controller.
