I've turned this into Sun as a Security problem, as well as a bug. So
far the only response I've gotten from Sun is that this problem was
opened a while back, but closed as not a bug. Well, I don't see that
happening this time since I have way too many SunOS 4.x machines running
around. Of course it's 'fixed in the current release of the OS', unless
you count SunOS 4.1.4 as current.

Ciao,
