I changed the location of the inbox like this
mail_location = maildir:/home/vmail/%u/mail:INBOX= 
/home/vmail/%u/mail/.Inbox
namespace {
   list = children
   location = 
maildir:/home/vmail/%%u/mail:INDEX=/home/vmail/%u/mail/shared/%%u:INBOX= 
/home/vmail/%%u/mail/.Inbox
   prefix = shared/%%u/
   separator = /
   subscriptions = no
   type = shared
}
namespace inbox {
   inbox = yes
   location = maildir:/home/vmail/%u/mail:INBOX= /home/vmail/%u/mail/.Inbox
   prefix =
   separator = /
   type = private
}
Also exteded my ldap queries to return the correct mail variable 
(=mail=/home/vmail/%u/mail:INBOX=/home/vmail/%u/mail/.Inbox).

Now an dovecot-acl inside /home/vmail/%u/mail gets used for newly 
created subfolders, which is very helpful. However if i share an users 
inbox now the hierarchie looks like this for an user with access.

shared/user
shared/user/Inbox
shared/user/INBOX

All three folders point to user's inbox. If i set 
mail_shared_explicit_inbox=yes "shared/user" is greyed out but the other 
two folders remain. Can someone here tell me what i did wrong to have 
three verisons of the inbox now?

Thanks in advance
