How to set the public key of the host?
Via the server’s command line console (ex: SSH) do a setkey command.
I set public key on a user, but the user is logging into wrong/old account
If you use keylist command, it will probably show the user somehow got multiple accounts with the same public key. Use the touchuser command to set the desired account as most recent, and then the user should auto login to it on their next connect.
