[Zope] Custom authentication page...

[Steve]

I'm just starting to look at Zope as a potential platform to implement a 
simple authenticated web site... however I do not want to face users 
with the standard web-browser dialogue, but rather my own log-in page.  
I've established how to restrict access based upon permissions etc... 
and I'm able to set/reset cookies based a form submission - but do not 
see how to integrate an HTML login page with the standard Zope security.

I've read that I should use the "Cookie Crumbler" product... but after 
I've added this to the folder that I intend to protect, I click on 
cookie_authentication (the default name for the "Cookie Crumbler" 
object) and I get the following error message:
--

An error was encountered while publishing this resource.

*Error Type: AttributeError*
*Error Value: aq_parent*

--

Is this a bug with "Cookie Crumbler" (version 0.3 downloaded from 
zope.org used against Zope 2.9.4, python 2.4.3, win32)?
Am I barking up the wrong tree in hoping to have a slick-looking "logon" 
page?  Is this something commonly done using Zope?  Is "Cookie Crumbler" 
the right product?  Would I be better hand-coding this myself?
