The openXDA uses Windows Authentication to determine you rights within the application. By default, the BUILTIN\Users group has administrator access, so you should be able to log in just fine with any valid Windows user account. If you are using Internet Explorer or Google Chrome, it should be able to log you in automatically using passthrough authentication. It must be asking for your credentials because it wasn’t able to do that. There are a couple things you can do to try to find the reason.
First, the issue could be that there is an error in the application preventing it from properly authenticating your user account or determine your roles within the application. If that is the case, there should be something in the openXDA.ErrorLog.txt file or the Windows Event Log that would give us more information about what that error might be. The openXDA.ErrorLog.txt file is located in the openXDA installation directory. The Windows Event Log can be viewed by launching the Event Viewer and navigating to
Windows Logs > Application.
Second, the response from the web server hosted within openXDA could give us more information about what is going on. The way to do this depends on your browser and/or what tools you have available on your system for sniffing HTTP traffic. For most, the easiest thing to do is open the developer tools in your browser and then use the Network tab to view the requests and responses seen by the browser. If certain HTTP headers are present or missing from the HTTP response, it can help to determine which code module is responsible for the authentication failures.
