Hm, I do not get this to work with the GUI. I do not try with CalDAV.

If I add only "delegate" perm for the secretary, the sec does neither see 
the calendar nor add any events.

If I add "show" and "delegate" perm, the sec may see free/busy information 
and can add events in _basic_ mode only, but these events are lost, they 
never get saved into the database. I do not get any error or notification. 
In dynamic mode, the sec cannot add events to the calendar at all.

If I share "delegate" perm for the secretary and "show" for "Object 
Creator", it's the same as above.

If I give "edit", it does not matter, if "delegate" is given, too. In both 
cases the newly added event has the sec as event_creator_id.

What's a working configuration for delegate? I use
kronolith                    4.2.5   stable
