I need to be able to login to a RHEL 6 server using rsh (please don't flame me about security, it's irrelevant in this particular instance) as root without having to enter a password. My procedure for setting this up works great in RHEL 5.x, but does not work in RHEL 6. I suspect this has something to do with PAM, but I'm inexperienced with how to use PAM. Can someone help me with this?

/etc/pam.d/rsh

auth      required   pam_rhosts.so
auth      required   pam_nologin.so
account   include    common-account
password  include    common-password
session   required   pam_loginuid.so
session   include    common-session

/etc/pam.d/rlogin

auth      required   pam_nologin.so
auth      [user_unknown=ignore success=ok ignore=ignore auth_err=die default=bad] pam_securetty.so
auth      sufficient pam_rhosts.so
auth      include    common-auth
auth      required   pam_mail.so
account   include    common-account
password  include    common-password
session   required   pam_loginuid.so
session   include    common-session

Thanks!
