Two authentication servers can be connected to a storage system. When the servers are connected, the server configurations must be the same, except for the IP address and the port.
If you search for a server using information registered in the SRV records in the DNS server, confirm that the following conditions are satisfied:
Note: For RADIUS servers, you cannot use the SRV records.
Because UDP/IP is used to access the RADIUS server, no encrypted communications are available, such as negotiations between processes. To access the RADIUS server in a secure environment, encryption in the packet level is required, such as IPsec.
