[Zope-DB] SQL, LoginManager and SkinScript.

[Jeffrey E. Hulten]

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?
