ACK!  To avoid confusion, you should refer to the remote machine as
the server, and the local machine as the client.  Or remote and local.
Which machine are you ssh-ing into?

Well, for starters, check the permissions on the identity.pub file,
the authorized keys file, the .ssh directory, and your home directory.
Make sure they conform to the specifications in the man page for sshd
on the server.  In general, all of those should not be
group-writable or world-writable, and should be owned either by the
user or by root.  That's probably what's getting you.  But it could be
other things too.  I recommend you thoroughly read the man pages for
sshd on both systems.
