Distributed installation of this add-on

This table provides a quick reference for installing this add-on onto a distributed deployment of Splunk Enterprise.

Splunk instance type Supported Required Comments
Search Heads Yes Yes The host must run a supported version of Windows and have access to the domain controller for the domain / forest that you want to get events. The configurations you make must be identical across the search head and all search peers.
Indexers On search peers only Depends The host must run a supported version of Windows. If the indexer acts as a search peer, then you must install it on all indexers that act as search peers. The search peers must have access to the domain controller for the domain / forest that you want to get events. Additionally, the configurations you make must be identical across the search head and all other search peers.

Universal Forwarders No No The add-on does not perform any function when you install it on this type of Splunk instance.
Light Forwarders No No The add-on does not perform any function when you install it on this type of Splunk instance. Also, light forwarder functionality has been deprecated and could be removed in a future version of the Splunk software.
