+deny_unknown
+.RS 4
+Defaults to off. If set to on then unknown (squashed) users will be denied
+access to the filesystem completely instead of just being squashed. Users are
+considered unknown by nodemap if the admin flag is off and the user is root, or
+trusted are set to off and the user is not mapped.

+Note: directory entries cached by a Lustre client may be visible to unknown
+users located on the same client, though the contents of the files will not be.

+audit_mode
+.RS 4
+Defaults to on, which lets clients record file system access events to the
+Changelogs, if Changelogs are otherwise activated. If set to 0, events from
+these clients are not logged into the Changelogs, no matter if Changelogs are
+activated or not.
+The reason not to record file system events from given clients is to prevent
+some nodes (e.g. backup, HSM agent nodes) from flooding the Changelogs.
