No offense but I don't think that you understood the general point
(probably my mail was too confusing).
With marking the secretary _is_ allowed to see the data, it (mostly)
says how he/she is supposed to deal with it wrt _other_ people.
If you do not want to have the secretary see the item, just remove
the permissions via access control. Which, as explained, happens
automatically in Outlook but not in Kontact.
Maybe a better example is a company wide memo. This would be marked
'confidential' so that people know that they are not allowed to tell
their out-of-company friends.
Seperate thing unrelated to permissions of the item (its basically
public inside the company).

Err. Which is intentional, did you actually read the sentence you
IMHO the real bug is that the Kontact UI does not make the user aware
of the fact that this is "just" a marker (only affects the iCalendar
CLASS property, no ACL settings).
In contrary, it explicitly labels the checkbox as "Access:" which is
just wrong. Should be "Sensitivity:".

Sorry, when I think about groupware I tend to think about multiuser
systems, which means shared folders ;-) And in a shared folder the
private (ACL, not marker) flag must be per user.
