This sounds like /etc/default/useradd has been modified.  The default
file created by Rocks is:

/etc/default/useradd:
# useradd defaults file
GROUP=100
INACTIVE=-1
EXPIRE=
SHELL=/bin/bash
SKEL=/etc/skel
HOME=/export/home

If the HOME variable is changed to /home (from /export/home) yes, it
will break useradd.  What does this file look like on your clusters?
