什么是可信连接？

Question

在SQL Server 2005（Trusted vs Windows Auth）方面，什么是可信连接？

Answer 1

A trusted connection is the same thing as using Windows Authentication in SQL Server 2005. Authentication is done by the domain, and authorization is handled by SQL Server.

SQL Server can also use its own logins, such as the sa user. These are both authenticated and authorized by SQL Server. They are only viable if SQL Server is run in Mixed Authentication Mode.

MSDN has a good article about choosing the right Authentication Mode . It's a good primer.

Answer 2

A Trusted connection means Windows Authentication.

SQL Server has two Authentication modes: Mixed and Windows Authentication Mode.

Mixed has the option of SQL server logins (username and password) and Windows Authentication.
