The home directories should contain the same files as the head node, which
to start with is probably just a bunch of .whatever files.
I have had problems with the passwordless ssh when I was fiddling around
with getting LDAP authentication set up, so you may have changed something
which fixed one problem but is now causing this one. Adding things to
hosts.allow should not be necessary for instance, though as far as I know it
shouldn't cause problems either.
After you were having set up problems, did you go back and start with a
clean OS install again? It shouldn't take nearly as long the second time :)
