[sync] Synchronize more devices with one horde account

[Raphael Studer]

I've used:
http://[MyHordeURL]/rpc.php (not rpc).

Path for contacts:
contacts

Path for calendar
calendar

There are two users on the server p1 and p2.
p1 was first synced with the funambol client, p2 was first synced with
the synthesis client.

With p1 I get a strange error, with p2 entries from phone are stored
on the server (but not vi verca).

Any further ideas?
