Authentication failed for user - Login and user are not the same

[Viroxken]

I'm not able to connect (SQL authentication) to a sql server database in which the login suser_sname() and the database user user_name() is not the same. In my case the login is mapped to dbo user.

Error:
_duckdb.InvalidInputException: Invalid Input Error: MSSQL connection validation failed: Authentication failed for user 'xxx' - check username and password

I'm able to connect to another database in the same sql server instance. In that case login and user are the same.
