You can use the command-line interface (CLI) to configure the system to use remote authentication.
If a user is configured on the system as a local user, only local credentials are used. Otherwise, users entering their password are authenticated against the remote service when they use the management GUI or the command-line interface (CLI). Their roles are determined according to group memberships defined on the remote service. If a user is configured on the system as a remote user with an SSH key, the user can additionally access the command-line interface by using this Secure Shell (SSH) key. Group memberships continue to be determined from the remote service.
