Not able to enable SSH user equivalency for RAC on RHEL 4

Question

Hi All,
I am trying to install oracle RAC 11g on RHEL4 (on VMware), I am using below document for reference.
http://www.oracle-base.com/articles/11g/OracleDB11gR1RACInstallationOnOEL5UsingVMware.php
Every thing went fine till "SSH user equivalency", but I am not able to SSH and SCP between servers without entering passwords.
I have tried removing .ssh folder & recreating pub file twice but it did not helped.
am i missing something?
Please advice.
Thanks,
Abhay.

Configure SSH on each node in the cluster. Log in as the "oracle" user and perform the following tasks on each node.
su - oracle
mkdir ~/.ssh
chmod 700 ~/.ssh
/usr/bin/ssh-keygen -t rsa # Accept the default settings.
The RSA public key is written to the ~/.ssh/id_rsa.pub file and the private key to the ~/.ssh/id_rsa file.
Log in as the "*oracle*" user on RAC1, generate an "authorized_keys" file on RAC1 and copy it to RAC2 using the following commands.
su - oracle
cd ~/.ssh
cat id_rsa.pub >> authorized_keys
scp authorized_keys rac2:/home/oracle/.ssh/
Next, log in as the "oracle" user on RAC2 and perform the following commands.
su - oracle
cd ~/.ssh
cat id_rsa.pub >> authorized_keys
scp authorized_keys rac1:/home/oracle/.ssh/
The "authorized_keys" file on both servers now contains the public keys generated on all RAC nodes.
To enable SSH user equivalency on the cluster member nodes issue the following commands on each node.
ssh rac1 date
ssh rac2 date
ssh rac1.localdomain date
ssh rac2.localdomain date
exec /usr/bin/ssh-agent $SHELL
/usr/bin/ssh-add
You should now be able to SSH and SCP between servers without entering passwords.
hope, this may helps you.
enjoy.
