How to setup a Data connection to the QRS API using Windows Authentication on the June 2017 release
Authenticating with a Windows user account
You can use a Microsoft Windows identity to authenticate requests to the Qlik Sense Repository Service (QRS) API. In this case, you must send requests via the proxy server URL.
When requests are authenticated this way, no certificates are required and the permissions of the Windows user are applied when the connection is made. This method can be used on the Qlik Sense server or to execute code remotely (however, the technology used to make the API call must support Windows authentication).
