CardDAV sync with other CLient than OSX Lion?

[geordy]

Hi,

I have installed OX Snapshot 6.20.1 Rev5 and installed the DAV modules. Now I want to use DAV to sync with Outlook and Android.
Yes, I know it's just developed for OSX at the moment, but I want to get rid of funambol. The current Android Funambol Client can't sync calendars, and installation is not as trivial as it could be. To many "hacks" are needed because of many incompatible versions.

Now to DAV. Calendar sync works just great with some 3rd party apps. Nothing to complain about. But CardDAV is not that good. Mailed with a developer of an Android CardDAV sync app. He wanted to implement support fpr OX in his App.
He told me OXs CardDAV implementation is not really compilant to CardDAV standard.

Syncing from OX to Android works (kind of). I get all contacts, personal and global, plus two entrys "Kontakte" and "Globales Adressbuch". Sync Android to OX doesn't work.

Here are some snipets the developer wrote me (sorry its German):

Die CardDAV-Implementierung von OX ist nicht so doll, wie es aussieht. Das Problem ist, dass die einzelnen OX
Adressbücher nicht auf CardDAV-Adressbücher gemappt werden (sie wie bei mehreren Kalendern), sondern auf so ne Art
Gruppen (aber das wiederum mit proprietären Attributen).
....
OX hat aber einen ganz groben Schnitzer in seiner CardDAV-Implementierung. Der Pfad / wird als Adressbuch Collection
ausgewiesen, da aber das eigentliche Adressbuch in /carddav/Contacts/ liegt ist das ein klarer Verstoß gegen den
Standard (Adressbücher in Adressbüchern sind nicht erlaubt).
...
Warum die Änderungen noch nicht zurück synchronisiert werden weiß ich auch noch nicht. Der Server liefert einen
Fehler 412 zurück was darauf hindeutet, dass das etag nicht stimmt.

Now to my Questions:
1. Will there be an CardDAV implementation that will be more standard compilant? When? :-)
2. I can see my webserver returns error 412 but I can see nothing in OX log that points to a failure.

Is there an option for debug-log for DAV?
Any hints?


Kind regards,
