PBIRS Authentication issue

Dear Support, 

Could you explain more and how I apply this to my current situation? I did change the Authentication Type to <RSWindowsNTLM />. 

For now, the domain controller is Server A. A is holding all user account information and got the policy setup. We have installed Power BI Report Server in Server B. We would like to use the same AD login credentials in Server A for Server B, especially the username and password. So we cannot export the user list from Server A and import them to Server B since passwords are encrypted.

We use “Join domain” method. We configure Server B to join Server A domain. So that I can create the local group in Server B and add the AD users from Server A in it. It also our ideal result and all working.

However, there is an issue. When we click manage of the Power BI report or open the Power BI report in Power BI Report Server, a message box appear, “An error has occurred. Something went wrong. Please try again later.” And nothing else showing and keep loading.

What can I do next?

Thank you very much!

Best Regards,

Gary Yuen
