I'm a school teacher and want to set up a folder structure of users in Zope consisting of school class names, such as 12ITSAS, and then individual folders at the next level down for each individual student, Student1, Student2, Student3 etc. I'm inexperienced with Zope but do have some background in programming. I would like the students to have read only and copy rights at the 12ITSAS level folder and manager rights in their individual, Student1, Student2 folders. In that way I can provide them with resources within the 12ITSAS folder that they can't change at that level but which they can copy and change at the level of their folders. I can't see how to do that efficiently using the Zope security model. When I provide students with Manager rights at the level of their individual folders (Student1, Student2 etc) then they can't access the 12ITSAS folder because that is at a higher level. And of course if I give them Manager rights at the 12ITSAS folder level then they can modify what I supply them and invade each others folders. Any assistance would be much appreciated. - Bill Kerr Woodville High School South Australia
