/etc/nscd.conf
This file is used to configure nscd (name service cache daemon). See the nscd(8)
and nscd.conf(5) man pages. By default, the system entries of passwd and
groups are cached by nscd. This is important for the performance of directory services,
like NIS and LDAP, because otherwise the network connection needs to be used for
every access to names or groups. hosts is not cached by default, because the mecha-
nism in nscd to cache hosts makes the local system unable to trust forward and reverse
lookup checks. Instead of asking nscd to cache names, set up a caching DNS server.
Network protocols, used by getprotoent; see the
protocols(5) man page.
