            sss_ssh_knownhostsproxy acquires SSH host
            public keys for host HOST, stores
            them in a custom OpenSSH known_hosts file (see the
            “SSH_KNOWN_HOSTS FILE FORMAT” section of
            sshd(8) for more information)
            /var/lib/sss/pubconf/known_hosts and
            estabilishes connection to the host.
        
            If PROXY_COMMAND is specified,
            it is used to create the connection to the host instead of
            opening a socket.
        
ssh(1) can be configured to use sss_ssh_knownhostsproxy for host key authentication by using the following directives for ssh(1) configuration:
ProxyCommand /usr/bin/sss_ssh_knownhostsproxy -p %p %h GlobalKnownHostsFile2 /var/lib/sss/pubconf/known_hosts
