I have a couple of users who have iCal setup using Caldav to see their own calendars plus a number of shared calendars.

The issue is that they keep getting alerts from other users calendars for events. Is this by design, or a bug? I wouldn't anticipate an alarm from iCal for an event that is in another person's shared calendar. If it's by design, is there a way to turn off shared calendar alarms?
