What does little lock on desktop icons mean?

Question

I have a fresh installation of Oracle Solaris 10, when I login as user root, desktop icons all look fine.

I created a new user calledhoward and logged in using howard. All desktop icons have a little "lock" on top right corner.

User howard belongs to group staff and additional group root.

What does the little lock mean?

Answer 1

It means that the currently logged-in user does not have write access to those files.
