SQL Server Management Studio error Execute failed: Login failed for user

I have a local installation of SQL Server Management studio. I created a SQL Server Authentication login and tested it. However when I try to connect with Knime i get the following error

ERROR Microsoft SQL Server Connector 2:1 Execute failed: Login failed for user

any help?

It would be simple to answer if you provide a screenshot of failed node configuration.

Hi izaychik63,
sure, sorry for not attaching a screen. The config is pretty basic because windows authentication seem to be quite a hassle so i used the sql server auth
When I log in to SSMS directly i got no issues but using knime i got the error

ERROR Microsoft SQL Server Connector 0:1 Execute failed: Login failed for user

java.sql.SQLException: Login failed for user ‘xyz’.

Did you install MS SQL JDBC Driver?

Thanks I have tried that but now the only difference is that the error message contains an additional client connection id

“ERROR Microsoft SQL Server Connector 0:1 Execute failed: Login failed for user ‘xyz’. ClientConnectionId:e493220b-63…”

Hi there @Daniel_Weikert,

did you manage to resolve your issue and connect?
