Brand new installation of horde, similar issues with SyncML. Client  
would receive new contacts and calendar items from horde, but anything  
created or changed client-side would not sync back. Any updates made  
to previously-synced items on the server side would also not sync to  
the client.

- Horde 5.2.2 (PEAR installation)
- Funambol Sync Client 10.1.6
- Outlook 2010 (14.0.7128.5000 x86)

Originally had similar 'HORDE [ingo] IMP is marked as authenticated,  
but no credentials can be found in the session.' in logfiles from  
previous testing, but now I'm getting the following:

-----------------------------

I tried different session handlers (builtin/filesystem/mysql) and all  
methods left the same entries in the log.

The Funambol log shows no errors in synchronization, and does record  
the correct amount of new/changed items in testing. It also doesn't  
try and re-send anything, even if the items didn't make it into horde  
in a previous sync, which would seem to indicate that horde is  
recording the synchronization tokens properly, but it isn't  
creating/updating the actual items.

I'll update here if I find a solution. We want to replace our antique  
Exchange environment with horde but this is a deal-breaking issue for  
us as we have a lot of users on Outlook 2010.
