Horde only does slow syncs with my N900 client (syncevolution), but  
other users have reported similar problems on the mailing lists. As  
Jan stated, it seems that Horde fails to read the timestamp of the  
last sync from the database.

I tried to produce a clean log. Here is what I did:

1. rm everything in /tmp/sync
2. horde log output set to "Debug"
3. dropped all horde_syncml tables and recreated them using the horde
configuration and deleted all turba contacts and calender items
4. deleted everything in ~/.cache/syncevolution on the n900
5. manually initiated slow sync with syncevolution with

'syncevolution --sync refresh-from-client  <myconfigname>'

That worked flawlessly.

6. Initiated a "normal" two-way sync with 'syncevolution <myconfigname>'

Same problem again. Horde can't seem to find the timestamp:

UNKNOWN:Previous sync found for database contacts; client timestamp:
UNKNOWN:Client requested sync with anchor timestamp 20110426T173321Z  
but server has recorded timestamp . Enforcing SlowSync

Attached to this bug there is a tarball which contains:

- Horde /tmp/sync folder contents (synclogs.tgz)
- Syncevolution output during slow sync (syncevolution_output_slow_sync)
- Syncevolution output during normal sync (syncevolution_output_normal_sync)
- content of the horde_* database tables (horde_syncml.sql)
