NIS+ to LDAP Migration Guide

Overview of NIS+ to LDAP Migration
Comparing LDAP and NIS+ Information Sharing
Chapter 110
LDAP-UX Client Services improves on this configuration information
sharing. User, group, and other network operating system configuration
information can be integrated with other identity information in other
organization-wide applications. The account and configuration
information is stored in an LDAP directory. Client systems retrieve this
shared configuration information across the network from the LDAP
directory. In addition, LDAP adds greater scalability, interoperability
with other applications and platforms, and less network traffic from
replica updates. Figure 1-3 shows a simplified LDAP-UX Client Services
Environment.

LDAP-UX Client Services supports the following name service data:
passwd, groups, hosts, rpc, services, networks, protocols, printers,
netgroup, automount and public key.
How LDAP-UX Client Services Work
LDAP-UX Client Services works by leveraging the authentication
mechanism provided in the Pluggable Authentication Module (PAM) and
the naming services provided by the Name Service Switch (NSS).
