Ubuntu 14.04, ctdb 2.5.3, samba 4.1.11. CTDB is working with IP takeover
between the 2 nodes. The machine is joined to the domain.
Any help with the following errors would be most gratefully received.

Id verify maybe with an few echo statements that all the CTDB variables from /etc/default/ctdb get passed to that script. Read you copied the samba start script from an wiki can be it assumes variables in /etc/sysconfig/ctdb.
