+# /etc/nsswitch.conf

+# An example Name Service Switch config file. This file should be
+# sorted with the most-used services at the beginning.
+#
+# The entry '[NOTFOUND=return]' means that the search for an
+# entry should stop if the search in the previous entry turned
+# up nothing. Note that if the search failed due to some other reason
+# (like no NIS server responding) then the search continues with the
+# next entry.
+#
+# Valid entries include:
+#
+#	nisplus			Use NIS+ (NIS version 3)
+#	nis			Use NIS (NIS version 2), also called YP
+#	dns			Use DNS (Domain Name Service)
+#	files			Use the local files
+#	db			Use the local database (.db) files
+#	compat			Use NIS on compat mode
+#	hesiod			Use Hesiod for user lookups
+#	[NOTFOUND=return]	Stop searching if not found so far
+#
+
+# To use db, put the "db" in front of "files" for entries you want to be
+# looked up first in the databases
+#
+# Example:
+#passwd:    db files nisplus nis
+#shadow:    db files nisplus nis
+#group:     db files nisplus nis
+
+passwd:     sss files
+shadow:     files sss
