Comment 1 for bug 1184354

Hello,
Sorry, but we do not support WebDAV sync yet. The "Online Synchronisation" only works with the Snowy REST API server atm.
I am aware that Ubuntu One is not hosting a sync server any more - could not miss that :-D
We are working hard to build a replacement for Snowy, called Rainy (https://github.com/Dynalon/Rainy/) and we will host a public syncserver with the support of http://monkeysquare.org/ as soon as it is stable.
Feel free to support us with either porting the existing webdav code for tomroid (https://blueprints.launchpad.net/tomdroid/+spec/webdav-sync) to our newest code-basis, or by hosting a Rainy server and reporting (and fixing) bugs for the server.

Sorry for the bad news!
Cheers,
Stefan
