+# Valid databases are: aliases, ethers, group, gshadow, hosts,
+# initgroups, netgroup, networks, passwd, protocols, publickey,
+# rpc, services, and shadow.
+#

+#
+#    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

+#
+# 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
+
+# In order of likelihood of use to accelerate lookup.
+passwd:      sss files systemd
+shadow:     files sss
+group:       sss files systemd
+hosts:      files dns myhostname
+services:   files sss
+netgroup:   sss
+automount:  files sss
+
+aliases:    files
+ethers:     files
+gshadow:    files
+# Allow initgroups to default to the setting for group.
+# initgroups: files
+networks:   files dns
