Maureen,

	This is not what I would term a "security hole".  This is quite
fixable, and should be by most competent administrators.  I would term this
as one of many stupid (too harsh?) things that vendors of OSs do when they
ship their product.  Very similar to shipping the OS without a root password
or any other number of vendor/administative login ids that come without a
password.  This I can sort of even see their point on, but again it falls to
the administrator to see that these things are put in proper form before
the system is given over to user consumption.
