Two for me very important issues for ownership: a) a non privileged user could see date for which he was not allowed ! b) how do i change the ownership of a folder in the Unix sense of chown ? I don't understand the new concept. My Problems are: a) we were able to log in as a non privileged user and view a Folder, for which acess was only allowed for the owner of this folder and no one else. How come and what did i do wrong ? Zope installation was new 2.2 and the folders and users were newly generated. c) When i want to change the ownership of a folder like chown in Unix: Superuser is not allowed, anyone else can only take, user can not give away so in my view 1. Both useres havbe to have access 2. User B takes ownership 3. USER B modifies acces so that user A can not anymore acess ????? thanks for any help Micha
