Alarms don't work for CalDAV
Last modified: 2013-02-21 05:21:12 EST
Description of problem:
Notifications don't work for CalDAV calendars. They do work for local calendar
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. make sure that "Display alarms in notification area only" checkbox in Edit -> Preferences -> Calendar & Tasks -> Alarms is checked and also all calendars are checked
2. create an event with alarm in CalDAV calendar
3. wait for time when alarm should trigger
alarm is not triggered
alarm should be triggered
for local calendar, alarm works
RHEL 5 bug: bug 473044
We spoke a bit about this on IRC and there is a problem with authenticated calendars. There was a bug about the same with Exchange calendars, and if I recall correctly then the resolution was to store calendar password, thus the evolution-alarm-notify process have it ready when needed (the process doesn't ask users for passwords, it's new in 3.3.x). David told me he does save passwords for his CalDAV calendar, thus this is about something else.
The other possibility, I can think of right now, is network unavailability. I suppose David's calendar is on VPN, and when the evolution-alarm-notify process is run on session start, then the VPN connection is not established yet, thus the process gets rid of the calendar and doesn't try to reconnect later. Restart of evolution-alarm-notify may prove the hypothesis, though when David tried then it didn't work for him either, he didn't receive any reminders from his CalDAV calendar.
I'll investigate this later, and let you know what I found through this bug report.

OK, after some investigation it turned out that the evolution-alarm-notify process uses wrong password component. While the calendar view uses either "auth-domain" property of the ESource (which is usually set on Groupware sources, like exchange), or the predefined "Calendar" component, the evolution-alarm-notify fallbacks to ESource's name instead, thus it cannot find password (it is requested to store passwords, otherwise alarm notification doesn't work), and thus the authentication fails and no alarms are shown.
I'm currently building a test package for you, thus if you could test it, then it'll be appreciated. https://brewweb.devel.redhat.com/taskinfo?taskID=4266335
