Open Source Document Management System | OpenKM

I am using OpenKM 6.3 on Windows 7 as well as on Windows Server 2008 R2 with mysql.
I want to modify security rights for a folder as well as for document. By default when we create a folder or upload a document then the security is automatically assigned. And provides right for everything to Admin, user who uploads it and to ROLE_USER. I don't want to provide any right to any role when we create folder or upload a document. Can you please help me out to do so... How can I achieve this? What will be the ways to do so...?

When you set grants into a folder, any element uploaded into automatically inherits the grants.

If you want to change actual grants to childs you got a check box at left bottom -> propagate what will apply any change to childs ( after the checkbox is selected ).
