2# /etc/nsswitch.conf
3#
4# An example Name Service Switch config file. This file should be
5# sorted with the most-used services at the beginning.
6#
7# Valid databases are: aliases, ethers, group, gshadow, hosts,
8# initgroups, netgroup, networks, passwd, protocols, publickey,
9# rpc, services, and shadow.
10#
11# Valid service provider entries include (in alphabetical order):
12#
13#	compat			Use /etc files plus *_compat pseudo-db
14#	db			Use the pre-processed /var/db files
15#	dns			Use DNS (Domain Name Service)
16#	files			Use the local files in /etc

20#
21# Commonly used alternative service providers (may need installation):
22#
23#	ldap			Use LDAP directory server
24#	myhostname		Use systemd host names
25#	mymachines		Use systemd machine names
26#	mdns*, mdns*_minimal	Use Avahi mDNS/DNS-SD
27#	resolve			Use systemd resolved resolver
28#	sss			Use System Security Services Daemon (sssd)
29#	systemd			Use systemd for dynamic user option
30#	winbind			Use Samba winbind support
31#	wins			Use Samba wins support
32#	wrapper			Use wrapper module for testing
33#
34# Notes:
35#
36# 'sssd' performs its own 'files'-based caching, so it should generally
37# come before 'files'.
38#
39# WARNING: Running nscd with a secondary caching service like sssd may
40# 	   lead to unexpected behaviour, especially with how long
41# 	   entries are cached.
42#
43# Installation instructions:
44#
45# To use 'db', install the appropriate package(s) (provide 'makedb' and
46# libnss_db.so.*), and place the 'db' in front of 'files' for entries
47# you want to be looked up first in the databases, like this:
48#
49# passwd:    db files
50# shadow:    db files
51# group:     db files
52
53# In alphabetical order. Re-order as required to optimize peformance.
