I am currently familiarizing myself with SQL Server security. During the process, I came across the following text passage.
Windows-level principals are generally domain and local server user accounts that authenticate to SQL Server using Windows authentication.
Source: Pro SQL Server 2008 Administration.
What does the author mean by "domain and local server user accounts", specifically "server user accounts"?
Does it mean the user account for the operating system on which, for example, SQL Server Engine is running?
