[CalendarServer-users] iMIP replies and Lighning interoperability (Update)

[Markus Stürmer]

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?

Regards,
Markus
