nss-ldapd 是一个 NSS 的模块用来查询 LDAP服务器的信息。
This module allows retrieval of information about Unix accounts, groups, hosts, and other information from an LDAP directory. It is a fork from the nss_ldap module to do some architectural changes. This implementation splits the functionality into an NSS part and a local daemon to do the lookups. This works around a number of problems in the original implementation.
