[zope2-tracker] [Bug 511294] [NEW] UnauthorizedBinding Context is not being handled at all by MultiAdapters

[Patrick Gerken]

Public bug reported:

In svn commit 24375,

http://svn.zope.org/Zope/trunk/lib/python/Shared/DC/Scripts/Bindings.py?rev=24375&r1=24352&r2=24375

happens a workaround for better Security handling.

Instead of throwing an Unauthorized Exception, it returns a Context that
will most probably throw an Unauthorized Exception later, while trying
to access a member.

But Nowadays, we can try to get a view with MultiAdapters, and these
throw an KeyError, that is then not handled as a Unauthorized Exception.
I wonder, if this workaround for Workflows can be removed. I mean its, 6
years now.

The issue materializes itself in Plone, the bug report there is this one:
