then you might want to copy id_dsa.pub (default file name) to authorized_keys2.
According to the man page: "$HOME/.ssh/authorized_keys is the default file that lists the public keys that are permitted for RSA authentication in protocol version 1 and for public key authentication (PubkeyAuthentication) in protocol version 2."
authorized_keys2 isn't needed (and hasn't been for a while now).
