# Verify that the server end of an SMB connection is correctly reset
# 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 releasing node
# should reset the server end of the connection.
