4 # An example Name Service Switch config file. This file should be
5 # sorted with the most-used services at the beginning.
7 # Valid databases are: aliases, ethers, group, gshadow, hosts,
8 # initgroups, netgroup, networks, passwd, protocols, publickey,
9 # rpc, services, and shadow.
11 # Valid service provider entries include (in alphabetical order):
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
17 # hesiod Use Hesiod (DNS) for user lookups
18 # nis Use NIS (NIS version 2), also called YP
19 # nisplus Use NIS+ (NIS version 3)
21 # See `info libc 'NSS Basics'` for more information.
23 # Commonly used alternative service providers (may need installation):
25 # ldap Use LDAP directory server
26 # myhostname Use systemd host names
27 # mymachines Use systemd machine names
28 # mdns*, mdns*_minimal Use Avahi mDNS/DNS-SD
29 # resolve Use systemd resolved resolver
30 # sss Use System Security Services Daemon (sssd)
31 # systemd Use systemd for dynamic user option
32 # winbind Use Samba winbind support
33 # wins Use Samba wins support
34 # wrapper Use wrapper module for testing
38 # 'sssd' performs its own 'files'-based caching, so it should generally
39 # come before 'files'.
41 # WARNING: Running nscd with a secondary caching service like sssd may
42 # lead to unexpected behaviour, especially with how long
45 # Installation instructions:
47 # To use 'db', install the appropriate package(s) (provide 'makedb' and
48 # libnss_db.so.*), and place the 'db' in front of 'files' for entries
49 # you want to be looked up first in the databases, like this:
55 # In alphabetical order. Re-order as required to optimize peformance.
61 # Allow initgroups to default to the setting for group.
