Replying to my self :
Dovecot 2.2 seems to have problem to replicate shared folders / public folders.
To workaround, I had to modify source file "src/replication/replicator/dsync-client.c" and change line 210 : str_printfa(cmd, "\tsync\t-d\t-N\t-l\t%u", DSYNC_LOCK_TIMEOUT_SECS); To : str_printfa(cmd, "\tsync\t-d\t-l\t%u", DSYNC_LOCK_TIMEOUT_SECS);
This way, replicator is using command : doveadm sync -u USERNAME -d -l 30 -U -s instead of doveadm sync -u USERNAME -d -N -l 30 -U -s (note : -N enable to sync all Namespace) Latest command would sync all user's Namespace (private / shared / public) and will failed, and user's mailboxes won't be replicated.
An option in replicator plugin's could be usefull to enable / disable sync of shared folders, sync of public folders, and sync of user's mailboxes.

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.
