The result is still nasty since it means the unauthorized error will 
always consider the user to be unauthenticated. I've implemented a 
workaround in NuPlone to fix that, see 
http://svn.plone.org/svn/collective/NuPlone/trunk/plonetheme/nuplone/skin/error.py 
. Perhaps something based on that will work for you as well.

Wichert.
