[Zope] Problem with std. user folder Authentication dialog

[vio]

How do I get rid of the Login dialog sent by 'user folder'?
I have a product which I want to allow public access to (without compromising my
site's security), but I can't get rid of the std. Login dialog. I tried to use
the calls from the Security chapter in ZopeDevGuide, but without apparent
effect: calls to security.declarePublic('myMethod') don't seem to work, as far
as I can tell.
Any hints would be appreciated.
