>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.
