"Distributing and Trusting SSH CA Public Keys"
==Wrong text ==
For remote user authentication, CA keys can be marked as trusted per-user in the ~/.ssh/authorized_keys file using the cert-authority directive or for global use by means of the TrustedUserCAKeys directive in the /etc/ssh/sshd_config file. For remote host authentication, CA keys can be marked as trusted globally in the /etc/ssh/known_hosts file or per-user in the ~/.ssh/ssh_known_hosts file.

== Corrections needed ==
per-user file should be ~/.ssh/known_hosts
global file should be /etc/ssh/ssh_known_hosts
