dovecot - Dec 2008 - dovecot 1.2 Alpha4 shared folders

Hi,

I'm trying to setup shared folders with alpha4 but didn't succeed until
now.
Here is my dovecot -n :

# 1.2.alpha4: 
/etc/dovecot.conf

# OS: Linux 2.6.26.5 i686 Mandriva Linux 
2009.0

  acl: vfile:/home/%%d/Maildir
  sieve: ~/.dovecot.sieve
  sieve_storage: ~/sieve

A list doesn't display any folder in Shared.
What should I put into /var/lib/dovecot/shared/mailboxes ?
Is the acl: vfile:/home/%%d/Maildir ?
Should I put some file(s) is the users Maildir directory ?

Thanks,

Diederick

Looks ok.

So you're using system users. Do the users have +rx permissions to other
users' maildirs?

Do all users have +rwx permissions to /var/lib/dovecot/shared?

%%d doesn't work here. If you're not going to use global ACLs, you can
just set "acl = vfile".

It doesn't show anything until there are shared mailboxes. Are there
any?

You shouldn't touch it. SETACL command updates it.

I'm not sure how well the shared mailbox support works with system
users, or how well it will ever work. You're going to have permission
problems. You could create dovecot-shared files with proper permissions,
but that file isn't automatically created by SETACL command and I'm not
really sure if it even should.

How do I setup these, symlinks ? Or is it in the acl ?

OK.

This means that you only tested it with a virtual user setup ?
If so, I can switch over to this setup although it is a lot overkill for 
only 5 users.
