+#!/bin/bash
+#
+# The nfs.rpc-auth-allow volume option is used to generate the list of clients
+# that are displayed as able to mount the export. The "group" in the export
+# should be a list of all clients, identified by "name". In previous versions,
+# the "name" was the copied string from nfs.rpc-auth-allow. This is not
+# correct, as the volume option should be parsed and split into different
+# groups.
+#
+# When the single string is passed, this testcase fails when the
+# nfs.rpc-auth-allow volume option is longer than 256 characters. By splitting
+# the groups into their own structures, this testcase passes.
