In the very beginning of my Zope career, I once "shot myself in the
foot" with a very stupid thing... I kept it to myself then but if we are
talking about Zope security settings and usability of the ZMI at the
same time, perhaps it is an ideal place to raise this issue.
If you use the famous manage_access page with all the checkboxes to set
permissions on an object, it then calls manage_changePermissions to
using POST method to apply your settings. The result is that
http://your_object_url/manage_changePermissions (without any parameters)
stays in your browser visited url history. Now imagine what happens if
you click this url by mistake being logged as someone with "Change
I guess changing the form method to GET is not going to be liked by
browsers that put additional restrictions on URL length. So I would
propose to introduce a basic request sanity check in the
manage_changePermissions itself. I cannot think of any use for resetting
all permissions and acquisition for everyone, so the easiest way to do
that is to simply check that at least something exists in the form:
def manage_changePermissions(self, REQUEST):
"""Change all permissions settings, called by management screen.
>> if len(REQUEST.form)<2: raise ...
fails = 
or something like that.

Well I said it was over and out but I have to respond to this latest
post. I appreciate the help here and will be trying out some of the
suggestions. Basically though, Zope permissions and security could be
made a lot more usable. It's far too technically focused and this is
the opinion of a few others as well. The whole ZMI interface could be
put through a usability re-design to be honest and that's not even to
comtemplate the security areas.
The ZMI is well known to be geeky. "For developers, by developers"
might be its motto. If you have some concrete suggestions, by all
means put them forth. Patches are even better.
Anyway, ACLs are ACLs. And if you don't know what you're doing, you
can get into trouble real fast. Ever tried managing file security on a
Windows machine with ACLs?
CMF (this includes Plone) provides a way to manage this complexity:
workflow states. Each workflow has a set of permissions it manages,
and a setting of these for each state. This is much more easily
comprehended than infinite fiddling with the ZMI Security tab.
Also, as I recall, there was a "private plone site" howto on
plone.org; dunno what happened to it.
