Active Directory Certificate Services: CRL Distribution Point

Hi,

I am trying to configure CRL Distribution Point in Active Directory via HTTP.

In Certification Authority, Properties, Extensions I have LDAP, HTTP, FILE. For the HTTP case "Publish CRL to this location" is greyed out.

If I try to access the HTTP URL that is published, i get 403. Forbidden Access is Denied.

Why is that? Do I need copy manually the CRL in the WebServer folder? Is there an automatic way to publish automatically CRL via HTTP?

Regards,

Antonio
