You did copy id_rsa.pub to authorized_keys:

cat .ssh/id_rsa.pub >> .ssh/authorized_keys

???

Also check /etc/ssh/sshd_config an /etc/ssh/ssh_config.  These files
need to allow public key logins.  Also, does /etc/ssh/sshd_config have
anything set for AllowUsers and/or AllowGroups?  All any/all of the
machines in question?
