Fedora directory users - Dec 2005 - REPLICA HAS NO UPDATE VECTOR ...

Hi,
 
I''m trying to configure FDS 1.0.1 with Active Directory.
 
I configure the Sync Agreement and the ''Full
Re-Synchronization'' works
well.
 
When i want to make an update : Send and Receive Updates Now, the
message "Replica has no update vector. It has never been initialized"
is
displayed.
 
What i have to do to solve this issue ?
 
Many thanks for your help.
Regards.
