[Zope] Security Gurus Wanted

18 Jan 2002

      Could someone have a look at the following 'Boring' class with the security functionality added (as described in ZopeBook/6.Security and some other products). Could 'security' machinery be broken in Zope-2.4.1 ? It surely doesn't seem to work as adverised, on my machine at least (Debian Linux 2.2, Zope 2.4.1 (source release) python 2.1.0, linux2). Tell me if it works on your installation.

#   SECURITY -   ====================================================
# here I played with '#'s, then simply tried to access 'index_html'
# after each security declaration,
# as user 'Anonymous', and noted the results on same line. 
# 'NOT-WORKING' simply means not working as advertised (allowed access when 
# it shouldn't, and vice-versa). As you can see, there are too many 
# 'NOT-WORKING' results. Do you come to similar results?
# My conclusion is that security declarations have no effect whatsoever,
# whether I declare something, then its oposite, I end up with the same
# result. This shouldn't be.
