[Zope] a LOT of users and roles

[Nils Decker]

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
