[sync] What works, what doesn't with SyncML?

[Tews, Shad]

 have just installed and setup Horde version Mnemo H3 (2.2-cvs). I am trying to get the wireless syncML stuff working but I am not having much luck. This is my environment.

Everything with Horde seems to work and function fine but trying to sync with a PDA or PDA emulator is not working. I have tried the following clients and have had limited to no success.
1) Funambol Outlook plugin 3.0.15 (just hung)
2) Funambol Outlook Plugin 6.0.14 (can sync some items to Horde but nothing syncs down)
3) Synthesis Client 3.0.2.3 for Windows Smartphone. (nothing syncs)
4) Synthesis Client 3.0.2.3 for Palm OS running on Palm Emulator. (Notes sync'd once but the Horde end had an empty title)
 
It seems that the server gets in an infinate loop as I can see it flipping between Processing and Waiting but it never really gets anywhere. The log files in /tmp/sync seem to have wbxml entries for the URL but it dones't look properly formed. 
 
I guess my biggest question is, do people have certain clients working and sync'ing reliably? If so, what clients are you using (versions etc) and what is the server setup? (OS and versions) I think I would be happy to have one type of client sync'ing contacts to and from horde consistantly. From there I can branch out to get the remaining stuff working and evaluated. Any help as to what to expect would be greatly appreciated.
 
thanks,
Shad
