nss-pam-ldapd

底下 OpenBMC 对nss-pam-ldapd 的描述

Bringing the LDAP authentication module support in openbmc stack requires to pull the nss-pam-ldapd which allows the LDAP server to provide the user, passwd, group info that we normally get from the /etc flat files.
openbmc auth stack 使用nss-pam-ldapd 来引入LDAP验证模组让我们能从/etc 平面文件中取得LDAP server 提供的 user, psswd, group 资讯。
