locking someone's account from reading the /etc/passwd file prevents login
from doing the thing it does, and thus the user is prevented from gaining
access.  Chroot'ing them to a jail is not too tough a task, but, then the
user won't accomplish too much work on the system without great efforts
being extended.  An Os these days lacking a shadow/passwd setup is vastly
behind the times.  TCB is not for everyone and every situation.
