+    description: |-
+      When the user databases are stored on a remote network service, NSS must
+      be configured to establish a secure link that allows, at minimum, to
+      authenticate the server and protect the communication channel.

+    notes: |-
+      A nsswitch service connecting to remote database is provided by sssd. This is checked in requirement R67.
+      Another such service is winbind which is by default configured to connect
+      securely to Samba domains.
+      Other relevant services are NIS and Hesiod. These should not be used.
