I would recommend using CTDB 2.5.1.  It has few important bug fixes.

Since CTDB 2.5, the default socket location has changed from /tmp to
/var/run/ctdb.  You should use that instead of the older configuration of
using /tmp/ctdb.socket.  For pre-compiled samba RPMs, you will need
additional samba configuration "ctdbd socket =  /var/run/ctdb/ctdbd.socket".

You usually don't need to change the permissions of CTDB socket since Samba
is run as root, it can access the socket.

Can you provide strace output when it fails?  You can start samba manually
as "strace -f -o /tmp/smbd.strace /usr/sbin/smbd -i -F"

Amitay.
