cat /etc/nsswitch.conf
#
# /etc/nsswitch.conf
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# Valid databases are: aliases, ethers, group, gshadow, hosts,
# initgroups, netgroup, networks, passwd, protocols, publickey,
# rpc, services, and shadow.
#
# Valid service provider entries include (in alphabetical order):
#
# compat Use /etc files plus *_compat pseudo-db
# db Use the pre-processed /var/db files
# dns Use DNS (Domain Name Service)
# files Use the local files in /etc
# hesiod Use Hesiod (DNS) for user lookups
# nis Use NIS (NIS version 2), also called YP
# nisplus Use NIS+ (NIS version 3)
#
# See `info libc 'NSS Basics'` for more information.
#
# Commonly used alternative service providers (may need installation):
#
# ldap Use LDAP directory server
# myhostname Use systemd host names
# mymachines Use systemd machine names
# mdns*, mdns*_minimal Use Avahi mDNS/DNS-SD
# resolve Use systemd resolved resolver
# sss Use System Security Services Daemon (sssd)
# systemd Use systemd for dynamic user option
# winbind Use Samba winbind support
# wins Use Samba wins support
# wrapper Use wrapper module for testing
#
# Notes:
#
# 'sssd' performs its own 'files'-based caching, so it should generally
# come before 'files'.
#
# WARNING: Running nscd with a secondary caching service like sssd may
# lead to unexpected behaviour, especially with how long
# entries are cached.
#
# Installation instructions:
#
# To use 'db', install the appropriate package(s) (provide 'makedb' and
# libnss_db.so.*), and place the 'db' in front of 'files' for entries
# you want to be looked up first in the databases, like this:
#
# passwd: db files
# shadow: db files
# group: db files
passwd: compat
group: compat
shadow: compat
# Allow initgroups to default to the setting for group.
# initgroups: compat
