I was not able to get a shared mailbox setup working using imapc. Tested
using mailboxes on the same server, as well as other servers.
We are using dovecot 2.2.10 from Centos 7, following the guide at
http://wiki2.dovecot.org/SharedMailboxes/ClusterSetup
imapc_host=192.168.5.5 #(Local dovecot server)
imapc_master_user= %u
imapc_password=TempPass
#imapc_user=te...@example.com # Added for testing.
namespace {
type = shared
separator = /
prefix = shared/%%u/
list = children
location = imapc:~/shared/%%u/
}
namespace { # used as a control to verify that shared mailboxes work
type = shared
separator = /
prefix = shared2/%%u/
list = children
location = sdbox:%%h:INDEXPVT=~/shared2/%%u
}
dict {
acl = mysql:/etc/dovecot/dovecot-sql_aggelos_shares.conf.ext
}
plugin {
acl = vfile
acl_shared_dict = proxy::acl
}
mail_plugins = acl
protocol imap {
mail_plugins = acl imap_acl
}
passdb {
driver = sql
args = /etc/dovecot/dovecot-sql.conf.ext
}
passdb { # for master user logins
driver = sql
args = /etc/dovecot/dovecot-sql_aggelos_aclmaster.conf.ext
master = yes
pass = yes
}
userdb {
driver = sql
args = /etc/dovecot/dovecot-sql.conf.ext
}
I can login using te...@example.com*t...@example.com (and see all of
test2's email), and it looks like it authenticates ok via imap, but
shared never shows up. No issues using shared2 which uses direct access
to the mailbox

It feels like the acl information in the vfiles is not available when
using imapc.
Our setup is as follows: (Currently does not use Dovecot Director, but
has the same issues where shared mailboxes may not be local on the server)
* Front servers, that are running dovecot (proxy to backend servers)
* Backend Servers, each handle their own local users.
Thank you
