+# Verify that CIFS connections are monitored and that CIFS tickles are sent.
+
+# We create a connection to the CIFS server on a node and confirm that
+# this connection is registered by CTDB.  Then disable the relevant CIFS
+# server node and ensure that the takeover node sends an appropriate
+# reset packet.
+
+# Prerequisites:
+
+# * An active CTDB cluster with at least 2 nodes with public addresses.
+
+# * Test must be run on a real or virtual cluster rather than against
+#   local daemons.
+
+# * Test must not be run from a cluster node.
+
+# * Clustered Samba must be listening on TCP port 445.
+
+# Expected results:
+
+# * CTDB should correctly record the connection and the takeover node
+#   should send a reset packet.
