[Zope] Need a clue with UserDb

[Tony McDonald]

Hmmm...I need some help here.

I have a folder, Upload whose contents are
index_html (no acquired permission on 'view', Anonymous User 'view' = 
no, Owner 'view' = yes). This is the DTML Document that does all the 
good stuff like listing files and allowing uploads. ie it's the 
'guts' of the system.
acl_users (a UserDb folder)
some assorted methods, ZSQL methods etc.

If I go to the URL like so
.../Upload/ (thereby calling the index_html DTML Document) I get the 
following traceback:
(in the body if the page)

An error has occurred.

and in the comment...

However, if I use a URL like so
../Upload/acl_users/docLogin
I get the lovely docLogin page that I composed and the person can 
authenticate happily, and as I made the ACTION part of the docLogin 
method to be /Upload/index_html the person can then start doing 
authenticated things.

I can also call ../Upload/acl_users/logout and the docLogout document 
is called and the cookie crumbles.

I thought I understood that UserDb would make authentication required 
for those users who don't have the 'view' role (ie Anonymous Users 
would get redirected to the docLogin document), obviously I *didn't* 
understand!

Is my problem due to the Zen-Void in my nut or have I found a ... bug!
