My work calendar is stored on my employer's Horde server. I also have my own owncloud instance running.
What I would like to do is store also my work calendar on my owncloud instance, and have a script which mirrors this calendar to my Horde account. I know that only I make changes to the calendar on the Horde server, so a one-directional sync from owncloud to Horde would be just fine.
Both owncloud and Horde support CalDAV; Horde in adition has some XMLRPC service. I have root access to the owncloud instance, but for the Horde server, I only have Horde's web login. I'd be grateful for any suggestions on how to do this synchronisation. Unfortunately, I haven't been able to find any solution yet.
