Customizing the update interval for NIS maps

By default, every 30 minutes (1800 seconds), adnisd uses adclient to connect to Active Directory. At the update interval, adnisd does the following:

  • Checks for network NIS maps explicitly defined in Active Directory to determine whether any records have changed.
  • Generates derived maps for any explicitly defined network maps that adnisd recognizes. For example, if the netgroup map is found in Active Directory, adnisd generates the netgroup.byuser and netgroup.byhost maps.
  • Updates the local cache with all changes to the network NIS maps.
  • Updates the local cache with changes to the derived maps for user and group information in the zone.

Note:   In most cases, updating the local cache of NIS data does not require you to restart any services.

In most organizations, the default update interval is adequate. In a more volatile or stable NIS map environment, reduce or increase the time between updates, as appropriate, by modifying the nisd.update.interval parameter in /etc/centrifydc/centrifydc.conf to specify a different number of seconds between updates; for example:

nisd.update.interval: 900
