Hi there, i need some hints about security with a large number of users and roles. We will have a lot of pages that are within 100 - 200 categorys. Any one of 5000 users will have the right to access documents within any combination of those categorys. Defining 200 roles doesn't seem right, because the security-tab would become huge. Does anybody know a better alternative? My idea was to create a new security-tab that is simpler. There will also have about 50 000 users that will be able to customize the site. There are products to sync a folder to a userfolder, but i don't know how zope handles that many objects within one folder. The other option would be to use a database aware userfolder and store any other info into the database too. Any comments? Thank you in advance Nils Decker
