I don't _know_ yet, but I suspect :^) I think that something is
running afoul of the new security checking inside the __call__
method of SQLMethod objects. If someone wants to use the Zope
debugger (the debugger is your friend!) to sniff into this, 
that is where you should start. Under the debugger, set a 
breakpoint in the __call__ of the DA class in 
lib/python/Shared/DC/ZRDB/DA.py. Stepping through should point
out what object is failing authorization. If anyone is so 
inclined, Michel P. has a very good debugger how-to:

...and let me know what you find out. I won't be around Friday,
but I was planning to put on the sherlock hat and work this out 
Monday - of course I hope someone beats me to it :^)
