# 30.9 LDAP

[LDAP](https://en.wikipedia.org/wiki/Lightweight_Directory_Access_Protocol) (轻型目录访问协议)是一个开放的、中立的、工业标准的应用协议，通过IP协议提供访问控制和维护分布式信息的目录信息。Spring Boot为任何兼容的LDAP服务器提供自动配置，同时也支持[UnboundID](https://www.ldap.com/unboundid-ldap-sdk-for-java) 的嵌入式内存中LDAP服务器。

[Spring Data LDAP](https://github.com/spring-projects/spring-data-ldap)提供了LDAP抽象。`spring-boot-starter-data-ldap`”Starter“方便地集合了依赖。
