Thank you for your post and I apologize for the delayed response!
Error Message:
ERROR_ADAL_WSTRUST_REQUEST_SECURITYTOKEN_FAILED: 0xCAA90014 Server WS-Trust response reported fault exception and it failed to get assertion. WS-Trust response: The requested resource requires user authentication.
From your error message, it looks like the issue might be that your device wasn't able to get a valid token from the federation service. In order to resolve the Server WS-Trust response error message, you'll have to check your Federation Server settings, and look for the server error code in the authentication logs. For more info.
Additionally, I found a related issue where a customer only had DeviceAuth
configured within the Global Auth Policy, but for Windows to obtain an Enterprise PRT, you'll need to enable FormsAuth
.
I hope this helps!
