Hi,

I'm trying to configure replication with dsync on Dovecot 2.2.5 (and 
latest nightly).

I did followed the guide at http://wiki2.dovecot.org/Replication

But I can get dsync-server working only if my users do not have access 
to shared mailboxes and / or public mailboxes which is problematic for 
our setup.

dsync-server is trying to create folders in public/ namespace :

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

If I run the command "doveadm -v sync -u my.user -f tcp:10.20.0.2:12345" 
mailboxes are sync correctly. No problem with public and shared mailboxes.

If i run the command doveadm replicator replicate 's.durant' or doveadm 
replicator replicate '*', I get plenty of Panic / Error for all users 
that can access Public mailboxes or Shared mailboxes.
