Shared folders not listed by IMAP

[Bambero]

Hello

I just upgraded my system and there is a problem with shared mailboxes.

When I use the doveadm command I can see shared folders:

doveadm mailbox list -u 'test at mydomain.pl'
Drafts
Sent
Spam
Trash
Shared
Virtuals
Virtuals/all
Shared/test2 at mydomain.pl
Shared/test2 at mydomain.pl/Sent
INBOX

But I can't see them over IMAP protocol.

Some config opts:

valid_chroot_dirs = /var/mail
mail_chroot = /var/mail

namespace {
  type = shared
  separator = /
  prefix = Shared/%%u/
  location = maildir:/%%u/Maildir:INDEX=~/Maildir/Shared/%%u
  subscriptions = yes
  list = yes
}

plugin {
  acl = vfile:cache_secs=5
}

plugin {
  acl_shared_dict = file:/var/mail/%i.db
}

protocol imap {
  mail_plugins = $mail_plugins imap_quota imap_acl imap_zlib
}


My version of dovecot is 2.2.10.
