 At this point, you have to copy the CA's public key into your server's authorized_keys file . This can't be done with ssh-copy-id as the CA's key is not loaded into you ssh-agent nor available in the ~/.ssh directory.
 You should have something like :
 <pre>
-    server:~# <b>cat .ssh/authorized_keys</b>
-    cert-authority ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAICAL7l1sQuKe4daLfKGZuiRPZZXquokQyH+p6utlZxZ+ Test CA

 Note the line beginning with cert-authority which is not common. For reference, read "AUTHORIZED_KEYS FILE FORMAT" chapter here : [http://man.he.net/man5/authorized_keys](http://man.he.net/man5/authorized_keys)
