If you read the script, it does what you just said. Why would I do it? It's 
quit a bit easier to run ssh-copy-id user@$i then it is to do the whole copy 
command, then append it to the current authorized_keys file. 

With that said, the method you talk about (using DSA does not work). On 
another server with identical /etc/ssh/sshd_config it works .. what's the 
deal?
