[mod_python] Problems with PythonAuthenHandler on Red Hat 8.0?

Hi. I recently stared working with mod_python. I am using the stock Red
Hat 8.0 installation which includes:

httpd-2.0.40-11
python-2.2.1-17
mod_python-3.0.0-10

I am having trouble with the example from "3.4 Now something More
Complicated - Authentication". My configuration in httpd.conf looks like:

<Directory /var/www/html/python>
        AddHandler python-program .py
        PythonHandler myscript
        PythonAuthenHandler myscript
        PythonDebug On
        AuthType Basic
        AuthName "Restricted Area"
        require valid-user
</Directory>

After getting prompted for the user and password, I get a "Server error!"
page and an entry in the /var/log/httpd/error_log:

"configuration error:  couldn't check user.  No user file?: /python"

Apache seems to want an AuthUserFile in there to read. The best I can
guess is there is a problem with the version of mod_python shipped with
Red Hat 8.0.

Any ideas?

Thanks in advance,
Jim
