I have this in my cluster

[root@phdns01 ~]# cat /etc/sudoers | grep root

## the root user, without needing the root password.

## Allow root to run any commands anywhere

rootALL=(ALL) ALL

## cdrom as root

rootALL=(ALL)NOPASSWD: ALL

[root@phdns01 ~]#

BTW, I have all servers id_rsa key set the same, and passwordless worked OK.
