What version of openssh do you have in the machine which you are trying to connect to, via keys? The command rpmquery openssh will tell you, if in a RedHat comparable system, or maybe ssh -v .
If you have an openssh lower than version 3 , the following rules apply for the machine that you are trying to connect to: $HOME/.ssh/authorized_keys2 to permit authentication for RSA with protocol SSH 1.3 and 1.5. $HOME/.ssh/authorized_keys to permit authentication for DSA and RSA with protocol SSH 2.0.
