Finally, I gave up for the moment. It seems scheduling with DCS
+Lightning just does not work as it should.
As long as Lightning is used by the organized of an event, everything
works nicely (after enabling caldav scheduling). But when getting an
invitation, Lightning is just not able to recognize the user in the
attendee list. This seems to be due to the urn-Scheme used by DCS,
because hacking the ics-file in the attendees inbox can fix that.
(There has also been a discussion on the dev-list - most caldav
servers seem to use email addresses instead of urn-s).
Although mentioning only Lightning, I also tried Sunbird (latest
release and nightly builds). After all it seems this is more a client-
side problem.
Are there any Linux clients that work with DCS and also support
scheduling at all?

After some more web searches and experiments…
CALDAV support in Lightning 0.9 is quite incomplete. Lightning
1.0pre is slightly better, but still not complete and quite
unstable. So internal inbox/outbox scheduling should not be expected
to work for now.
For iCal I noticed that it
1) uses SOME email account for sending replies, but not the one the
invitation was sent from
2) uses the email address given in the Addressbook, not of the
invited attendee
After getting that as desired, also iCal reply end up with
exceptions.AttributeError: 'DirectoryPrincipalResource' object has
no attribute 'calendarUserAddresses'
I'd really like to know if others have the same error message or if
iMIP is working for them without problems.

Hello!
I'm trying to configure DCS on openSUSE 10.3 for a mixed Linux/
MacOS environment using XML file authentication.
There is few information available about DCS / Lightning
interoperability. It seems Lightning does not processing scheduling
requests in the scheduling inbox on the server, and does not send
invitations through DCS either. Was someone sucessful in getting
that working, or is that not yet supported in Lighning?
I got the iMIP scheduling in DCS only partially working: Known
users are asked internally (for iCal, see above), and external
users get an invitation email. Problems arise when DCS tries
interpreting and injecting email replies. I use the builtin mail
templates and have enabled plus-addressing on the mail server. I've
added an entry to the XML file for the com.apple.calendarserver
and the respective GUID to the »principals with "DAV:all" access«.
Depending on the client (both most recent version) I use to create
the reply email I get the following errors:

After adding an cuaddr to the calender user entry, I also got
errors when trying to schedule an event.
