All.... here is my log.....
Steps
1. ssh-keygen  -t rsa ,2 keys formed
2. copy .pub file to unix server
3.cp *.pub authorized_keys
  chmod 600 authorized_keys
  cp id_rsa.pub authorized_keys2
   chmod 600 authorized_keys2

sftp -v -v -v user4567@serverloc3
it is asking for a password.... even though I have no parapharase setup for testing.Am I doing any thing wrong
