# /etc/nscd.conf
#
# An example Name Service Cache config file. This file is needed by nscd.
#
# WARNING: Running nscd with a secondary caching service like sssd may lead to
# unexpected behaviour, especially with how long entries are cached.
#
# Legal entries are:
#
# logfile <file>
# debug-level <level>
# threads <initial #threads to use>
# max-threads <maximum #threads to use>
# server-user <user to run server as instead of root>
# server-user is ignored if nscd is started with -S parameters
# stat-user <user who is allowed to request statistics>
# reload-count unlimited|<number>
# paranoia <yes|no>
# restart-interval <time in seconds>
#
# enable-cache <service> <yes|no>
# positive-time-to-live <service> <time in seconds>
# negative-time-to-live <service> <time in seconds>
# suggested-size <service> <prime number>
# check-files <service> <yes|no>
# persistent <service> <yes|no>
# shared <service> <yes|no>
# NOTE: Setting 'shared' to a value of 'yes' will accelerate the lookup,
# but those lookups will not be counted as cache hits
# i.e. 'nscd -g' may show '0%'.
# max-db-size <service> <number bytes>
# auto-propagate <service> <yes|no>
