NSS-PAM-LDAPD is a Name Service switching module and a plug-in verification module. It allows your LDAP server to provide user accounts, groups, host names, aliases, network user groups, and you will typically get any other information from the ETC flat file or NIS, and allow you to authenticate to an LDAP server.
NSS-PAM-LDAPD 0.8. The change in the default properties used by the 4 version group members adds additional checks before returning the referenced shadow cipher information, increases connection timeout processing, supports large UID and GID values, handles too large values correctly, and has multiple minor bug fixes.

About LDAP
LDAP is a Lightweight Directory Access Protocol, the English full name is Lightweight Directory Access Kyoto, generally referred to as LDAP. It's based on the X.500 standard, but it's much simpler and can be tailored to your needs. Unlike X.500, LDAP supports TCP/IP, which is necessary for accessing the Internet. The core specifications for LDAP are defined in the RFC, and all LDAP-related RFCs can be found in the Ldapman RFC Web page.
