[Dovecot] Question about folder sharing

[Achim Gottinger]

Hi,

I run dovecot (2.1.7) on debian wheezy in conjuniction with postfix, 
samba4 (as ldap backend) and sogo. I configured folder sharing but have 
an few issues.
With my current config users can share the inbox and other folders. If 
the acl allows creatings subfolders this does work for all folders 
beside inbox.

What i want to archiev is the following:

If an user shares his inbox, others should be able to create subfolders 
and those should inherit the inboxe's acl. All subfolders of inbox 
should appear as folders at root level and not as subfolders of the inbox.

I thought this can be done by setting the prefix of namespace inbox to 
INBOX/. I did this and changed the IMAP Server Folder setting in 
thunderbird to INBOX (like it was earlier when i used courier). Now 
subfolders created at rootlevel or as subfolders of the inbox appear on 
rootlevel in thunderbird but they do not inherit the acl's from inbox. 
Is there an way to achive this?
