nscd service:
Name Service Cache Daemon. It handles password and group lookups for running programs and caches the information for the next query.

Now lets see the manual of nscd service.
Manual nscd:
NAME
/usr/sbin/nscd - name service cache daemon
DESCRIPTION
Nscd is a daemon that provides a cache for the most common name service requests. The default configuration file,
/etc/nscd.conf, determines the behavior of the cache daemon. See nscd.conf(5).
Nscd provides cacheing for the passwd(5), group(5), and hosts(5) databases through standard libc interfaces, such
as getpwnam(3), getpwuid(3), getgrnam(3), getgrgid(3), gethostbyname(3), and others. Each cache has a separate TTL
(time-to-live) for its data; modifying the local database (/etc/passwd, and so forth) causes the cache to become
invalidated within fifteen seconds. Note that the shadow file is specifically not cached. getspnam(3) calls remain
uncached as a result.
OPTIONS
--help will give you a list with all options and what they do.
NOTES
Nscd doesn't know anything about the underlaying protocols for a service. This also means, that if you change
/etc/resolv.conf for DNS queries, nscd will continue to use the old one if you have configured /etc/nsswitch.conf
to use DNS for host lookups. In such a case, you need to restart nscd.
