BIND error "permission denied"

Problem :
Error found in log file,

general: error: dumping master file: master/tmp-cFRWfFf7ah: open: permission denied

while doing a "rndc", "/etc/rc.d/named restart" or "/etc/init.d/named restart".


Solution :
e.g.

chown -R bind:bind /var/named/etc/master

Voila !!!
