Fail to Authenticate User

Symptom

When opening Kepion in a browser, the following error message appears: Failed to authenticate user.

Enable Windows Authentication on Home Edition

If you are using Windows Home edition, this feature does not come as an option and will need to be enabled by running a script in the Windows Command Prompt. In order to update the Windows Authentication Feature, we will need to find the appropriate filepath. The naming conventions of the folders and files may vary (Camel casing, all lower case, all upper case, etc.).

Run the Command Prompt as an Administrator.

Enter this Command into the window.

cd %SystemRoot%\servicing\packages

There are a lot of files within the Packages folder. The query below limits the scope of the search by using the first part of the file name and the file type.

dir *Microsoft-Windows-IIS-WebServer-AddOn-2-Package*.mum* /s

Note: The needed item is the file that does not contain 'en-US' In the above example, the file is called Microsoft-Windows-IIS-WebServer-AddOn-2-Package~31bf3856ad364e35~amd64~~10.0.18362.815.mum.

Now that we have all the components of the filepath, we should be able to navigate to the required file.

dism /online /norestart /add-package:%SystemRoot%\servicing\Packages\Microsoft-Windows-IIS-WebServer-AddOn-2-Package~31bf3856ad364e35~amd64~~10.0.18362.815.mum

Enter the above line into the Command Prompt.

When the operation has completed successfully, uninstall and then reinstall Kepion so the changes can take affect. 

Enable Windows Authentication on Pro Edition

If this happens in a newly setup environment, please make sure the IIS Windows Authentication feature has been turned on.

Otherwise, it may relate to an issue with the browser cache. Try clearing the cache, or using another browser to open Kepion.
