  • nscd: Class to manage nscd, Linuxs Name Service Cache Daemon.

Recommend reading the man page, NSCD.CONF(5). This module allows for parameterization of all options specified in the man page.

The module assumes that you want to set enable-cache to true for each of the services (passwd, group, hosts, and services). If this is not the case, you can disable the cache on a per service basis.

To use this module simply include ::nscd

  • Amazon Linux 2015
  • Amazon Linux 2016
  • Amazon Linux 2017
  • Debian 6
  • EL 5

Compatibility with Dell Authentication Services

When using nscd in combination with Dell Authentication Services (QAS/VAS) [1] it is recommended to turn off caching of passwd and groups.

nscd::passwd_enable_cache: 'no'
nscd::group_enable_cache:  'no'
