couple of points

jon may be right as regards problem being with pam

BUT - as the problem is with /bin/login you MAY have been hacked (esp
with root issue)

my understanding is Fvh updates to current version if rpm is already
installed (ie: good for updates maybe not so good for replacing hacked
binary)- I would try -Uvh -force utli-linux

there is a pm howto on LPP

few points to think on and look at
