dovecot - Mar 2013 - shared folders and "subscriptions = yes"

Example (dovecot 1.2.15):

,-[dovecot.conf]
| namespace public {
|    separator = /
|    prefix = management
|    location = maildir:/path/to/management
|    subscriptions = yes
| }
| 
| namespace public {
|    separator = /
|    prefix = sales
|    location = maildir:/path/to/sales
|    subscriptions = yes
| }
`-----

To have all IMAP-Users automatically updated their shared folder
structure I use "subscriptions = yes".
This works with the side effect, that all IMAP-Users can see _all_
folders in every namespace even if they do not have "lookup" access.
This is of course not wanted.

Is it possible to have dovecot check the ACL file in the root of a
namespace before it parses the subscrptions file?

regards
Lars

I guess it could be checking ACLs for subscriptions when they're coming from
a public namespace with subscriptions=yes. See if you can implement it. :)
