So my latest bzr http://people.samba.org/bzr/jmcd/SAMBA_3_0-pw.bzr/ has this
changed.  I didn't change the vampire code to not clear out the passwords,
but if you agree this is the right way to treat a zero in this field, I'll
fix the vampire code too.  I'm pretty sure we just interpreted it
incorrectly before.
