password not checked on screen unlock

[Sam]

On a system upgraded from 12.04 to 14.04:

When "don't ask for password on login" is checked for a user, previous screen locking would still require a password - the preference only applied to logins.

Now light locker(?) is showing a password dialog box, but it will accept any (or no) password for screen unlock, just as for login.

This might be a good change, but it was surely unexpected, and I found the previous functionality (being able to NOT require the PW for login but still require it for screen unlock) very useful, even if it might seem odd on the surface.
