rhel6 rsh as root

Hi,

Any one managed to configure rsh connection as root in RHEL6.x?

All work as charm in other version of RHEL how ever the 6.X PAM version is a bit different hence .....prompt for password :(

(Note: SElinux disabled / modified pam rsh+rlogin / removed /etc/securetty  / added ++ to /etc/hostst.equiv / added ++ /root/.rhosts - all the same settings i did from RHEL 7.3 ! )

Thanks !
