I have been having a problem I cannot get around with Zope 2.4.0,
Python 2.1.1, LoginManager (latest), ZPatterns (p2) and a SQL
database. I followed the instructions I found on zope.org and all of
the SQL methods work as expected. However when I change storage to
"Objects are loaded by accessing attribute ______" and set it to the
field in both the database and the skinscript called 'login'. I
throws the following traceback.

Traceback (innermost last):

And reports a KeyError... Any thoughts?
