About:
Libnsl provides the public client interface for the Network Information Service (NIS), formerly known as Yellow Pages (YP), and NIS+. It is a crucial system library that enables applications to query and authenticate against centralised directory databases for user, group, and host information. This package is essential for systems that need to integrate with legacy or existing NIS network authentication infrastructures.

Key Features:

Provides client libraries for NIS (YP) and NIS+
Enables centralised user and host authentication
Essential for legacy UNIX network integration
Maintained interface for system authentication

Use Cases:

Integrating Linux systems into an existing NIS domain
Centralising user account management across a network
Migrating legacy infrastructure while maintaining authentication

Alternatives:

LDAP / SSSD – Modern, more scalable alternatives for directory services, though they require different configuration and server setups.
