如果您使用集成安全性，则必须授予应用程序池活动目录帐户访问SQL Server数据库的权限。这里有一些提示：

您使用的帐户必须是在Web服务器和数据库服务器上均有效的活动目录帐户。如果您在同一台计算机上，则本地帐户将可用。
为了向您的网站分配身份，请在IIS中找到应用程序池（“应用程序池”下的网站设置），然后在应用程序池设置中找到“应用程序池标识”属性。将应用程序池标识设置为您选择的活动目录帐户。
在SQL Server中，创建一个映射到您的活动目录帐户的SQL用户
创建用户后，可以授予该用户访问数据库的权限

当然，这些步骤中的每一个步骤都有许多细节需要注意。

我还应注意，以上所有说明均假定您要使用标准登录名来设置数据库。另一方面，如果您要使用正在浏览站点的用户的Active Directory凭据向SQL Server进行身份验证，则将要使用IIS模拟而不是上面概述的步骤。 This article解释了假冒的基本知识。
