How to connect from an account to Microsoft SQL Server using Visual Studio 2019 C# windows forms?
I was able to connect via

cn.ConnectionString = @"Data Source = ALEKS\SQLEXPRESS;Initial Catalog = Test; Integrated Security = True";

I do not understand how to connect from a user account. The condition is that the user first starts a session and connects to the database, the account is bound to the domain.
