The documents (.pdf) that this document links to are located in a
password-secured directory (requires user/password/domain). When you click on a
link, however, you are not asked for your credential. Instead, you are
presented with an error that begins, "401.3 Unauthorized: Unauthorized due to
ACL on resource". MS IE 5.5 does ask for the credentials, and the documents are
accessible once credentials are given.
Sorry, but I don't know what software provides the access control. Not being a
programmer, I don't know if this could be a problem with that software.
Steps to Reproduce:
1. Go to URL
2. Click on any "download it" link
Actual Results: Complete error:
"HTTP Error 401
401.3 Unauthorized: Unauthorized due to ACL on resource
This error indicates that the credentials passed by the client do not have
access to the particular resource on the server. This resource could be either
the page or file listed in the address line of the client, or it could be
another file on the server that is needed to process the file listed on the
address line of the client.
Please make a note of the entire address you were trying to access and then
contact the Web server's administrator to verify that you have permission to
access the requested resource."
Expected Results: Should ask for User name, Password, and Domain. Once
provided, it should load the requested document.
This server use an authentification from Microsoft = NTLM
Mozilla currently supports only the web standard "Basic Auth.."
