A few things to look for: Make sure .ssh and authorized_keys files are permissioned to 700 and 600 respectively. If they are wide open then ssh will skip them. Check /var/log/secure on both machines. That may give you a clue ssh with -vvv (or just -v) and see if you get errors. I just had the same thing and my problem was .ssh permissions. Hope this helps.
