Authentication SQL Server

[alibaba]

Dear Community,

I am about to connect Power BI to my SQL database. Firstly I have created a local user on the SQL server and it worked properly to connect to the databses on the server from PowerBI - SQL Server autehntication.

Now I would like to change to a new user with windows authentication but it fails with the message: "The authentication with the provided information failed. Try again"

• The user login via windows authentication on the SQL server works pretty fine
• Only the connection via PowerBI fails

Did I miss something regarding the permissions of the user on server and database level?

Thanks in advance,

Alex

@amitchandak thx for the quick reply!

I have now also installed SSMS on my local machine (there I also use PowerBI) and tried to connect to the Server and get an error:

A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - Die Zertifikatkette wurde von einer nicht vertrauenswürdigen Zertifizierungsstelle ausgestellt.) (.Net SqlClient Data Provider)

HI @alibaba,

What windows authentication account did you configure on your database? The device which you install the SQL server or the device which installed the power bi and try to connect to the SQL server?

@alibaba , On the machine you have power bi, are you able to login to SQL Server via SSMS using windows auth?

if not, then check that first
