dovecot - Jan 2007 - Shared folder

Hi,

first.. i'm new on this list :-) and use dovecot 1.01rc17 under fedora 
core 5.
And i read the list of the last 4 moth and didn't found answers to my 
questions........

now i work with shared folders and got it running on the following 
configuration:

namespace private {
  seperator = .
  prefix   location = maildir:/srv/imapd/user/%u/maildir
  inbox = yes
}

namespace public {
  seperator = .
  prefix = Public.
  location =  
maildir:/imapd/shared/public/maildir:CONTROL=/imapd/user/%u/shared-settings/public/control:INDEX=/imapd/user/%u/shared-settings/public/index
  hidden = no
}

location is one line :-)

I have different questions to this configuration:

if i use "hidden = no" at the private namespace, the complete
namespace
isn't viewable, if i use "hidden = yes" i see the prefix
"private" at
the foldernames in my emailclient. Shouldn't be a non existing hidden 
option the same like "hidden = no"?

if use / as the seperator like dokumented at the wiki it doesn't work. 
with a dot like the seperator at the directories for the emailfolder it 
works.

is there a way to implement ACL for virtuell user in this configuration?  

The namespace could be a very interesting idea to give other user access 
to the own mailbox (e.g. for holiday), but for this each user need it's 
own acl-file which he can change.... And the special folder like Inbox 
must be viewable from another user.

The both last could be realized with an option like "ACL = 
/imapd/user/%u/rights" to include an file with acldefinition at the 
namespacedefiniton.
Another way could be a option like "ACL_R = user, user, group, group" 
inside of the namespacedefinition with definition of user and group 
outside of the namespacedefintion.
For me a LDAP request would the best way :-) i realize the complete 
emailconfiguration with ldap.

Looks ok.

You haven't configured "private" prefix anywhere, so they're
probably in
the mailbox names themselves..?

Yes, it defaults to no.

Why? Probably a client problem.

I'm thinking most of your problem are probably related to client
problems or possibly the mailbox names themselves.

See "Check that it finds other mailboxes" in
http://wiki.dovecot.org/TestInstallation

Try with that instead of with IMAP clients, and see if it works then as
expected.

Well, Dovecot doesn't currently really support these kind of shared
mailboxes, but you might be able to kludge it:

With ACL plugin you can create dovecot-acls file to the maildirs that
you want to share to others. http://wiki.dovecot.org/ACL

Then you could create some new namespace like:

namespace shared {
  seperator = .
  prefix = Shared.
  location = maildir:/srv/imapd/user/%u/maildir/shared
  inbox = yes
}

Then the shared/ directory would contain symlinks to the other users'
maildirs that you want to access. Anyway remember then that if you
delete dovecot-acls file or don't load the ACL plugin, the user has full
access to the mailbox..
