Hello
When an attendee have permissions (either read or write) on the  
organizer calendar, the ITIP 'accept-import' doesn't work correctly.

In imp/lib/MIME/Viewer/itip.php, 'accept-import' :
- first try to find an existing event through an export (from  
calendars with read-access)
- if an existing event is found, it tries to replace it (requiring a  
write-access).

If the attendee have a read permission on the organizer calendar:
- an existing event is found (from the organizer calendar)
- the replace action fails with an error message.
- a new event is added to the attendee calendar.

If the attendee have a write permission on the organizer calendar:
- an existing event is found (from the organizer calendar)
- the replace action succeeded.
- no event is added to the attendee calendar.

As a workaround, we can check for an existing event not from all  
calendars with read-access but only from the calendar where the  
attendee adds its events (Kronolith::getDefaultCalendar(PERMS_EDIT);

Regards
