N Printing Meta Data Not Genrating with Local User

[rohitk1609]

Hi Techies,

I have Qlik Sense Sep SR2. I have created one local user  ironman on Qlik Sense server and assigned token to it and made it root admin.

I have created one virtual proxy with prefix extclient with forms auth and linked central proxy to it.

when I login to https://machinename/extclient/hub with  .\ironman I can login fine and view the app.

Then, I created one new connection in N printing, added proxy as https://machinename/extclient/ and App Id and run verification

It gives me warning or  error as  The "Identity" and the Qlik NPrinting Engine service account are a Windows domain user. 

Now when I press meta data refresh button it gives me error. I checked the logs and below is what I found

identity=.\ironman. ERROR: System.Exception: Cannot find a Sense app with id 7e9a59b2-3454-4a05-8672-1b47f3736c4f↓↓↓↓Server stack trace: ↓↓   at Engine.Navigator.QlikSense

My question is: Can we make N printing connection with a local user ? if yes what things I need to care or set so meta data generate fine ?
