Azure Data Factory: Server connection error

Carlo Lodola 0 Reputation points


Data Source: Storage container: File uploaded Authentication method: Access key

Destination : SQL Server managed instance


Linked Service connected to the SQL Server managed instance , SQL Authentication , test connection successful

I have created a simple pipeline to copy data from the source to a table in the server (destination)

Server side I have user Admin set as DB sys admin permission to connect to SQL

Based on the error below , it appears to be indicating it is a firewall issue? Linked Service is successful when i do a test connection

If everything is under the same resource group , I presume a firewall is not the issue?

Any idea's? Managed instance I cannot see any settings for a firewall in the portal

    SQL Server Error 18456 indicate a login authentication error:

    Testing the linked service checks the ability to reach the SQL endpoint but does not validate the ability to login and perform operations

    Please check user credentials are correct by connecting to your SQL Server Managed Instance directly using the same username and password..

    Managed Instance supports both SQL Server Authentication and Azure Active Directory Authentication. Make sure the SQL Server Managed Instance is set to the correct authentication mode that aligns with the credentials you're using.
