Then the only alternative I know is an SQL user -- a user
with login and password registered inside an MSSQL instance.
You can pass his credentials via -U and -P.

I don't know. Login to your MSSQL instance via Management
Studio and see what users are present under
<instance> -> Security -> Logins
If there are no SQL users (which is strange) go ahead and
create one, with all the required permissions. In my
experiece, however, there is always an administrator-user

Since you said you do not want authentification by a Windows
user, it cannot. Create a proper MSSQL user.
