Looks to me like you need to set the server to use RSA authentication rather than
password.  You can make the client more verbose (-v, I guess) to show you the
authentication process and whether it is even trying your RSA key.

Look at the man page for sshd.  I think there are 2 settings - one which enables
authentication types and one which says which are required.  IIRC the order is
important, and for simplicity the two lists should be identical.

HTH,
