First you'll need to know what kind of dict paths the code uses. ACL
plugin uses these paths:

shared/shared-boxes/anyone/$owner
shared/shared-boxes/user/$user/$owner
shared/shared-boxes/group/$group/$owner

$owner is the user who is sharing the mailbox. $user and $group are the
users/groups who the mailbox is being shared to.

Next you need to decide how those paths are mapped to SQL. You've
currently mapped only the /user/ part. You could probably combine the
user and group by making that part in the path a $type
(shared/shared-boxes/$type/$id/$owner) and adding a new "type" column to
SQL table that would contain either "user" or "group". But perhaps a
cleaner solution would be to add a whole new table for it, something
like:

map {
    pattern = shared/shared-boxes/group/$group/$owner
    table   = shared_dict_groups
    value_field = status
    fields {
        group = $group
        owner = $owner
    }
}

And something similar for "anyone" if you want to enable it.

Hopefully that works, I haven't tried it. :)
