I have only my Sony to test so far. I tried to get an activesync log,  
but that didn't work for me..
So i activated the general_log in /etc/mysql/my.cnf and there i can  
now see the traffic.
Just for testing, i added an unique key on the table turba_objects,  
this prevented the dublicates,
but the sync never ends.. - that is correct behaviour :-)

Can you tell me, which key is used to get the match between server-  
and client-Contacts?

Ich have a vcardfile on my mobile with at least 535 contacts that i  
exported on my device as a backup in nov 2014.
In Android contacts, i do an import from this file and select the  
horde exchange account to add the contacts to.. some object_photos are  
in there too...

i will investigate further and try to get a correct sync log..
