[Dovecot] strange Folder in subscription list (was: Imap Ghost Folder)

[Sascha Zucca]

Hi list,
here's the complete Problem for easy reading again.
Can someone reproduce this?

I have a strange "ghostfolder" when using
shares/%%n/
as prefix for shared namespace.
If i swith only this setting to
shares/%%u/
everything is just as wanted, only then the prefix is very long, so i 
would prefer the name.



dovecot --version
2.1.7

dovecot -n

log_timestamp = "%Y-%m-%d %H:%M:%S "
mail_location = maildir:/var/vmail/%%d/%%n/Maildir
mail_plugins = acl
mail_privileged_group = vmail

   quota = dict:user::file:/var/vmail/%d/%n/.quotausage
   sieve = /var/vmail/%d/%n/.sieve
}
protocols = imap pop3 sieve
service auth {
   unix_listener /var/spool/postfix/private/auth {
     group = postfix
     mode = 0660
     user = postfix
   }
   unix_listener auth-userdb {
     group = vmail
     mode = 0600
     user = vmail
   }
   user = root
}

Thank you very much for your help
