Note: |
The use of LDAP (Lightweight Directory Access Protocol) is mainly for locating various entities such as organizations, individuals, and resources like files and devices within networks, both public and private. It offers a streamlined approach compared to its predecessor, DAP, by having a smaller code footprint.

允许未经身份验证的攻击者从域中检索信息，例如完整的用户、组、计算机列表，用户帐户属性和域密码策略。这是一个传统配置，从Windows Server 2003开始，只有经过身份验证的用户才被允许发起LDAP请求。
然而，管理员可能需要设置特定应用程序以允许匿名绑定并提供比预期更多的访问权限，从而使未经身份验证的用户可以访问AD中的所有对象。
