+Verify that  'ctdb setvar NoIPTakeover 1' stops ip addresses from being failed 
+over onto the node.
+
+Prerequisites:
+
+* An active CTDB cluster with at least 2 active nodes.
+
+Steps:
+
+1. Verify that the status on all of the ctdb nodes is 'OK'.
+2. Use 'ctdb ip' on one of the nodes to list the IP addresses being
+   served.
+3. Use 'ctdb moveip' to move an address from one node to another.
+4. Verify that the IP is no longer being hosted by the first node and is now being hosted by the second node.
+
+Expected results:
+
+* 'ctdb moveip' allows an IP address to be moved between cluster nodes.
