SSH Public Key Problem

[SimonMac]

I have a server, and two clients, I have created added the public key from client 1 to authorized_keys on the server and it works a treat, when I try to add the public key from client 2 to the same file but appending the new key below the first, I can still connect from client 1 but not client 2 as i get the error message

"Permission denied (publickey)."

Is what I am trying to do possible?

Yes.

Just make sure you put all of what is in client 1 id_rsa file, then all of what is in client 2 id_rsa file.
It should work. Sometimes it's actually the authorized_keys2 file.

The file permissions under the .ssh directory on both client 1 and client 2 will need to be tight. 600 / "rw-------" should do it but check the man page as I can't remember exactly.
