The problem with this solution is that there are shared folders for
different groups in Shared and dovecot will return an internal error
when trying to list a mailbox for which the user doesn't have read
permissions. See this thread for details:
  http://thread.gmane.org/gmane.mail.imap.dovecot/23528

That's why I had to write a post-login script that dynamically adds only
those directories as seperate namespaces to which the current user has
read-access.

Btw. I found out that if I create an empty directory
"Shared/<mailboxname>/.INBOX/", Mails in "Shared/<mailboxname>" (not
those in ".INBOX") are shown as a subfolder named INBOX in the client.
(Mails in "Shared/<mailboxname>/.INBOX" are ignored.) Maybe there is a
way to persuade the client to show those INBOX-Mails directly in
"Shared/<mailboxname>"?
