[turba] 401 Error when accessing via Android client CardDAV-Sync

[Dominik Erdmann]

Hello,

I saw in my Apache logfiles that all my three Android clients enters a 
401 (unauthorized) error when they accessing via the client 
CardDAV-Sync. See below attached log entries. The first one contains the 
error. Conspicuous is that the user name determined by HTTP 
authentication is missing.

Now my question: Do you know such entries? Is it possible to avoid these 
entries? Is there any option in Horde or the client?

=> The synchronization seems to work fine!
(I'm using latest horde-git)


Thanks,
Dominik
