False. nscd applies to all nameservice that goes through the service
switch, which is essentially all nameservice under Solaris.
Almost certainly you want to uncommment the
enable-cache hosts no
line from /etc/nscd.conf, otherwise round-robin DNS will not work,
among other things.
It is foolish to cache names in *both* named and nscd on the local
machine.
