I am migrating from courier. Migration worked well so far, I can access my maildirs with roundcube, with quota and sieve filters fully functionnal. Now I need to enable maildir sharing and can't figure out how to properly configure dovecot since my setup is a little different.
First the setup
Virtual users. Maildirs are in /var/vmail/domain.tld/username/. There is no Maildir subdirectory, the Maildir is directly layed out in the home directory. So we have : home = maildir. In the configuration it is translated as :
userdb {
args = uid=vmail gid=vmail home=/var/vmail/%d/%n/
driver = static
}
mail_location = Maildir:~/
The Maildir for a.chaouche looks like this :

You can tell I am migrating from courier because courier's files are still there, in addition to dovecot's.
.notifs is a folder containing many subfolders like .notifs.Webradios, .notifs.Kaspersky etc.
Next the folder I wish to access
so [email protected] wants to access a folder that belongs a.chaouche@backup.domain.tld to another virtual user, that is in another (virtual) domain (still on the same computer though)

root@messagerie[10.10.10.20] /var/vmail/backup.algerian-radio.dz/a.chaouche #
You can see I have put a dovecot-acl file in there, here's its content :
root@messagerie[10.10.10.20] /var/vmail/backup.algerian-radio.dz/a.chaouche # cat dovecot-acl
[email protected] lr
root@messagerie[10.10.10.20] /var/vmail/backup.algerian-radio.dz/a.chaouche #
Now the configuration
Here I have enabled the acl plugin for lmtp and imap
mail_plugins = " quota acl"
protocol lmtp {
mail_plugins = " quota acl sieve quota"
}
protocol lda {
mail_plugins = " quota acl sieve"
}
protocol imap {
mail_plugins = " quota acl imap_quota imap_acl"
}
Here's how my users database is configured
userdb {
args = uid=vmail gid=vmail home=/var/vmail/%d/%n/
driver = static
}
Here I specify that acl should be enforeced with vfile (dovecot-acl file)
plugin {
acl = vfile
[...]
}
Here I tried to a shared namespace called partage, I'm not sure what I did here was correct :
namespace partage {
location = maildir:%%h:INDEX=~/%%u
prefix = shared.%%u.
separator = .
type = shared
}
is the location allright ? is the INDEX allright (I don't know what that's for)
Finally, here's how mail_location is configured.
mail_location = Maildir:~/
Full configuration file

Errors
No errors in the logs, except I don't have the desired behaviour.
The desired behaviour is :
The behaviour I get instead is :
