[Samba] CTDB: Failed to connect client socket to daemon.

Sat Aug 16 07:52:04 MDT 2014

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.

1. connect to socket error:
