I would consider making the permissions of the user's home directory
as 000 - this should prevent the user from logging in; if not, then
mv the dir to a holding area.  If you don't have a home directory, then
you can't log in, at least on all the systems I've worked with.
[All non-BSD, but I imagine that they should be the same].
