    After following your steps, It’s still asking for password. On one machine, was already present and able to do passwordless ssh on most of other client machines but not able to do on one. The one on which, these steps didn;t worked has “.ssh” folder with 700 permission and inside that “authorized_keys” file only with 640 permission. Nothing else is present, I just used following command as file was already present:
    cat .ssh/ | ssh ‘cat >> .ssh/authorized_keys’

    Still asking for password. Can you please help. I have restarted sshd also from my client machine.
