Limitation of csvweb script .?

Question

Apache HTTP Server

OS ubuntu , installed cvsweb , when I visit cgi-bin/cvsweb/ the data I need is displayed, I need to restrict this page with a password, the script itself is in /usr/lib/cgi-bin/ , there is /etc/cvsweb.conf and /usr /share/cvsweb(icons. css)
In apache2.conf

<Directory "/usr/share/cvsweb">
    AuthType Basic
    AuthName "Administrative zone"
    AuthUserFile /etc/cvsweb/.htpasswd
    Require valid-user
</Directory>

There is .htaccess

AuthName "Private area."
AuthType Basic
AuthUserFile /etc/cvsweb/.htpasswd
Require valid-user

Still opens the page
