[kronolith] Caldav server scheduling - is it present and can it be disabled?

[Sebastian Arcus]

You might have to bear with me as my knowledge in this area is rather 
basic. If I understand correctly, the CalDav standard has the 
"calendar-schedule" extension available, which if implemented, allows 
the server to send out calendar event invites, and prevents the client 
from doing so. This might, or not might be the same as the iTip 
functionality - I'm not sure.

Bottom line is that when I connect Thunderbird to a Horde calendar over 
CalDav, I can't tick the box in Thunderbird which allows the Thunderbird 
end to send out event invites. Does anyone know if:

1. Kronolith currently implements the "calendar-schedule" CalDav extension?

2. If yes, is there any way to disable it - to allow Thunderbird to send 
the event invites?

Any info much appreciated
