Unable to Automate SSH authentication

[Rahul Tidke]

Hello,
    I am configuring Fedora Core 6 and CentOS5.3 for automatic SSH 
authentication, ssh version is OpenSSH_4.3p2, OpenSSL 0.9.8b, I  have  
executed following commands  but still both systems prompt me for 
passwords instead of using public keys.

ssh-keygen -b 1024 -t dsa (on both hosts with empty pass phrase)
ssh-agent $BASH (on both hosts)
ssh-add /root/.ssh/id_dsa (on both hosts)
created "authorized_keys" file in /root/.ssh directory on both the hosts 
and copied (exchanged) id_dsa.pub keys to it.
SSH is open on both the hosts.

Now it should login automatically without prompting for passwords; but 
it still prompts for password, what is going wrong here? I have tried 
disabling password authentication in /etc/ssh/sshd_config but no help.
