前言:

SQL Server 有两种身份验证:一种是WIndows身份验证,Windows身份验证使用Windows上的帐号,并利用其安全令牌进行验证。一种是SQL Server验证,使用SQL Server里面定义的帐号进行身份验证。

实现:

1、在SSMS中,右键【实例名】,选择【属性】,然后找到【安全性】页:

 【Windows身份验证】仅接受WIndows帐号,这个是默认打开并且不能关闭的。【SQL Server和Windows身份验证模式】接受WIndows和SQL Server帐号。

2、如果【Windows身份验证】已选,你可以创建SQL Server扽股,但是不能使用,切换身份验证需要重启服务。

原理:

在安装过程中,SQL Server会要求选择身份验证,Windows身份验证是默认的,并且是建议设置,因为不仅能简化管理,并且具有更加高的安全性。你不能禁用Windows身份验证,仅在访问的用户超出本地网络或者可信任域的环境时才使用SQL Server身份验证。

SQL Server帐号在SQL Server内部创建,身份验证和密码验证都由SQL Server负责。

被推荐的方案是使用Windows身份验证,并且在活动目录中定义组,把组添加仅SQL Server中。
