[Zope-CMF] Login to a members only portal

[Lars Schwabe]

Hi,

I want to create a members-only portal, and I followed the suggestion in 
the faqs at the cmf-documentation pages: I removed the permission 
"access content information" and "view" for anonymous via the ZMI. Now, 
only registed members are allowed to visit the site. They are promted 
for username and password in the dialog, but after authentification the 
first page they see is the web login form. How can I ensure that 
authentification is ONLY via the dialog and not via the web form?

Many thanks,
    Lars
