I am using a C# program to access a Virtuoso Sparql Endpoint (sparql-auth). I installed the latest version 7 of the Open Source edition. In my C# program, I use HttpClient with Basic Authentication. Virtuoso expects a Digest Authentification. How can I change the authentication method for the sparql-auth endpoint to Basic Authentication?
In Virtuoso Conductor, go to Web Application Server > Virtual Domains & Directories. You should see two table entries with a symbol in the first column. Click on it in the row of the HTTP Host {Default Web Site}. You will get a subtable. In the row of the Logical Path /sparql-auth click on Edit.
In the following window, find the header Authentication options. In the DropDown field Method, select Basic. Click Button Save Changes at the bottom of the window.
