[Q]How do I disallow the user 'anonymous' to view the contents of a certain folder?

Hi I would like to disallow the unser 'anonymous' to view the contents of a certain folder X while at the same time create a general user (with a password) which has the rights of the user 'anonymous' and is allowed to view and edit the folder X. What do I already know? server user inspect gives me a dictionary of the users (instances of SWUser) The testcase SWSecurityTests setup shows how to create a couple of permissions and to assign them to a role. Then a user is created and the role added. What I do not know is how to do the link between a user (and his role) and a certain folder. I would like to know as well how to access the permissions of a certain folder. server root permissions does not work. Thank you for the answer in advance Hannes
