In the Password Expiry Days
box, enter a number of days from today that you need your users' passwords
to expire. If there are any users who do not have a password, they
will also be forced to enter a new password.
- If this is the first time the expiry days has been set, all users'
passwords will be set to expire on the same day.
- If this is not the first time the expiry days has changed, users'
password expiry dates will be changed only if the calculated date
is before any existing expiry date. For example, if the box is set
to '20' on the 01/12/2010, users with expiry dates later than 20/12/2010
will be reset to 20/12/2010. Those users with expiry dates before
20/12/2010 will not be reset.
