   8 Prerequisites:
   9
  10 * An active CTDB cluster with at least 2 nodes with public addresses.
  11
  12 * Test must be run on a real or virtual cluster rather than against
  13   local daemons.
  14
  15 * Test must not be run from a cluster node.
  16
  17 * Clustered Samba must be listening on TCP port 445.
