CGI scripts traditionally get a predigested version of the headers the client
hands in. On many web servers, this _doesn't_ include the authentication
headers, which are crucial for handling password authenticated parts of your
website. Most servers will try and handle this information themselves, and
only hand the CGI script a new header, 'HTTP_REMOTE_USER', IIRC, that contains
the name of the authenticated user. This is desireable for many CGI scripts
when you don't want to have to code authentication libraries.
However, it is a pain when you have a system like Zope, that _is_ very capable
of handling this kind of authentication by itself. For different servers,
different tricks need to be employed.
On Apache, you can use a rewrite rule to make a copy of the Authorization
header and pass the copy in as 'HTTP_CGI_AUTHORIZATION'. On IIS, if you
specify no password protection for the PCGI stub, it gets handed the proper
headers quite nicely. IIS does interfere with the Zope 401 status message,
you'll need to switch that off. On Roxen, I believe there is a configuration
setting called 'Raw user info' for this. And Netscape requires a NSAPI plugin
to pass on the information.
Now, it sounds like Website doesn't pass in the Authorization header either.
Unfortunately, I don't know enough about Website Pro to be able to say wether
or not you can make it pass the header anyway, and what tricks are needed to
make it so. You will need to consult the Website Pro manuals for that. I hope
that my explanation has given you enough pointers to help you out here.
There is an alternative to passing in the Authorization header however, and
that's having Zope use REMOTE_USER. Your webserver will then do the
authentication, set the REMOTE_USER variable, and Zope will try and find a
User object that matches that user name. See doc/WEBSERVER.txt for more info
