Debug shared namespace issues

[Kees van Vloten]

Hi Team,

I am still having troubles with the shared namespace.

mail_shared_explicit_inbox = yes
namespace {
     type = shared
     separator = "~"
     prefix = shared~%%u~
     location = 
maildir:/srv/mail/vmail/example.com/%%n/store:LAYOUT=fs:FULLDIRNAME=0_FolderContent:NO-NOSELECT:UTF-8:INDEXPVT=/srv/mail/vmail/example.com/%n/index_shared/%%u:CONTROL=/srv/mail/vmail/example.com/%%n/control:VOLATILEDIR=/srv/mail/vmail/example.com/%%n/volatile
     hidden = no
     list = children
     subscriptions = no
}

To rule out ACL issues (for now), I have added:

plugin {
     acl = vfile
     acl_shared_dict = file:/srv/mail/dovecot/lib/shared-mailboxes.db
     #acl_defaults_from_inbox = yes
     acl_user = %n
     acl_ignore_namespace = shared~
}


The client imap communication looks like this:

The client shows the shared user, but no content.
I am using Sogo to test and sometimes Thunderbird to verify it is not a 
Sogo specific issue.

I have currently set these debug options in Dovecot:

auth_verbose = yes
auth_debug = yes
mail_debug = yes

Unfortunately this is not enough to get a clue.

What more can I do (other debug options?) to figure out what is going on?
