A daemon which handles passwd, group and host lookups for running programs and
caches the results for the next query. You only need this package if you are
using slow Name Services like LDAP, NIS or NIS+.
This particular NSCD is a complete rewrite of the GNU glibc nscd which is a
single threaded server process which offloads all NSS lookups to worker
children; cache hits are handled by the parent, and only cache misses start
worker children, making the parent immune to resource leaks, hangs, and crashes
in NSS libraries.
It should mostly be a drop-in replacement for existing installs using nscd.
