>Description:
	The synopsis basically covers it.  I use the password expiration
	field to lock out user accounts when the time they've paid for
	runs out, but they can still use ftp to access them.  A big
	security hole for those who want to take advantage of it for
	free web hosting.

>How-To-Repeat:
	Set expiration date on an account to a date in the past, then
	ftp localhost and login as that user.
