authentication, so that local authentication can be used as a fallback mechanism if the primary and
backup RADIUS servers are unavailable. Additionally, users who are configured locally but are not
configured on the RADIUS server are still able to log into the device. Authentication methods are
attempted in the order they are listed until the first successful authentication result is returned;
therefore if you want to ensure that users are authenticated first through the RADIUS server, and only
authenticated locally if the RADIUS server is unavailable or if the user is not defined on the RADIUS
server, then you should list the RADIUS authentication method prior to the Local users authentication
method.
See User authentication methods for more information about authentication methods.
If the RADIUS servers are unavailable and the AnywhereUSB Plus device falls back to local
authentication, only users defined locally on the device are able to log in. RADIUS users cannot log in
until the RADIUS servers are brought back online.
