Nsswitch.conf

nsswitch.conf

A system administrator usually configures the operating system's name services using the file /etc/nsswitch.conf. This file lists databases (such as passwd, shadow and group), and one or more sources for obtaining that information. Examples for sources are files for local files, ldap for the Lightweight Directory Access Protocol, nis for the Network Information Service, nisplus for NIS+, dns for the Domain Name System (DNS), and wins for Windows Internet Name Service.
