No, a user should be free to change and add keys as they see fit. The sshd already implements access control if there is a chance authorized_keys has been tampered with. If you really want to verify all changes to users authorized_keys file, change the ownership so users can't modify the file but still read it. -- I prefer the dark of the night, after midnight and before four-thirty, when it's more bare, more hollow. http://a.area51.dk/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
