I have a SonicWall SSL-VPN 2000 hardware VPN box that users use to connect to a 2003 Server. The server hosts e-mail, files, and Sharepoint. You can create links to internal web services and it passes the credentials to the resource. When I follow a link to the sharepoint intranet site, I get the following error:
TTP/1.1 401 Unauthorized Content-Length: 1656 Content-Type: text/html Server: Microsoft-IIS/6.0 WWW-Authenticate: Negotiate WWW-Authenticate: NTLM WWW-Authenticate: Basic realm="server.nwi.local" X-Powered-By: ASP.NET MicrosoftSharePointTeamServices: 18.104.22.16868 Date: Thu, 15 Jun 2006 16:09:02 GMT Connection: close You are not authorized to view this page
You do not have permission to view this directory or page using the credentials that you supplied because your Web browser is sending a WWW-Authenticate header field that the Web server is not configured to accept.
I assume it's something to do with how the device is passing the credentials to the web server. What settings would I need to change on the IIS site to allow it to accept WWW-Authenticate headers?
