I have a basic website written in Python Django, hosted on IIS 8.5. The website is used in the company intranet with Windows Authentication.
Accessing the website through a browser gives no problems for authentication. However, making use of a simple web API to retrieve data for reporting purposes is giving problems.
I'm trying to load a URL into Excel which supplies data in CSV format (Data -> From Web). Disabling IIS Windows Authentication and using Anonymous works perfectly. However, enabling Windows Authentication does not work as Excel says 'credentials are incorrect'.
The URL response is a simple HttpResponse object with CSV data. Nothing weird or complicated happening.
Any idea where to troubleshoot this? My IIS knowledge is limited in this regard.
