[Dovecot] acls not copied when creating subfolder of private INBOX

Using brand new dovecot 2.1.5 I still have a problem with the inheritance of
acls.

Setting:
- maildir with private INBOX and public folders.
- users maildir directory (/home/mail/user/ahelmcke) contains dovecot-acl file
- public folders root directory (/home/mail/Fax) contains dovecot-acl file

When creating a subfolder of the public folder the dovecot-acl files gets copied
to the subfolders directory as expected.
When creating a subfolder of the users INBOX the dovecot-acl files does /not/
get copied to the subfolders directory.

Debug output:

doveadm -Dv mailbox create -u ahelmcke Fax/Buhhhh

 i am not sure ,but but i think that works like designed


http://wiki2.dovecot.org/ACL



..
ACL Inheritance

Every time you create a new mailbox, it gets its ACLs from the parent
mailbox. If you're creating a root-level mailbox, it uses the
namespace's default ACLs. There is no actual inheritance, however: If
you modify parent's ACLs, the child's ACLs stay the same. There is
currently no support for ACL inheritance.

Namespace's default ACLs are read from "dovecot-acl" file in the
namespace's mail root directory (e.g. /var/public/Maildir). Note that
currently these default ACLs are used only when creating new mailboxes,
they aren't used for mailboxes without ACLs.

I do read this as: when creating a new mailbox; acls are copied from parent.
This it what it does for public folders but /not/ for the private ones. So in my
opinion at least it is not working as
documented.

i think its missunderstandable written

this is what counts i think

http://wiki2.dovecot.org/ACL
...
"There is currently no support for ACL inheritance"
..

public folders are special cases....
it makes sense to have inheritance as default acl

but this may not be a good idea as default at users folders

read the list archive about this stuff, i cant remember all
but Timo wrote some about it, at last ,develop of that feature may be
still be not finshed

Maybe http://hg.dovecot.org/dovecot-2.1/rev/e8b80e0767ac fixes this as well?

if i create a folder , set acls to it ( by manual i.e edit dovecot-acl)
same acl are copied to its subfolders

if the folder gets its acls from global-acl the acls arent copied to its
subfolders

As far i remember Timo is thinking about redesign acl config , check the
list archives
