Install the Splunk Supporting Add-on for Active Directory

This topic provides instruction on how to install the Splunk Supporting Add-on for Active Directory.

Where to install it

The Splunk Supporting Add-on for Active Directory is designed to be installed across a distributed Splunk platform deployment. It can be installed on:

  • Search heads
  • Search peers (indexers) when you want to distribute LDAP queries across those peers. Like the search head, the search peers must have access to Active Directory for this to work. See Install SA-LDAPsearch on the search head and all search peers in this manual for details.
  • Heavy forwarders. The Splunk Supporting Add-on for Active Directory does not perform any function when you install it on a universal or light forwarder.
