If an authorization server works together with an authentication server, the user groups that are registered in the authorization server can be assigned to a user for Device Manager - Storage Navigator.

You can use the authentication server without knowing the host names and port numbers, if you register the information of the authentication server as an SRV record in the DNS server. If you register multiple numbers of authentication servers to the SRV record, you can determine the authentication server to be used, based on the priority that has been set in advance.
If the affiliated user group registered in the external authentication server and the user group registered locally in the storage system are different, the user group in the storage system has higher priority.
