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.|
|Heavy Forwarders||Yes||No||The host must run a supported version of Windows. In this configuration, you can route events from the add-on to other Splunk Enterprise instances based on target index, or filter the data to extract only the events you want.|
|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.|
Distributed deployment compatibility
This table provides a quick reference for the compatibility of this add-on with Splunk distributed deployment features.
|Distributed deployment feature||Supported||Comments|
|Search Head Clusters||Yes||Configure your search head cluster first, then perform an installation of the add-on. The cluster replicates the configurations.|
|Deployment Server||Yes||You can deploy the add-on to search heads.|
What are the other prerequisites?
The 'admin_all_objects' Splunk account capability
The Splunk Supporting Add-on for Active Directory requires the
admin_all_objects capability to read storage passwords. The
admin user has this capability by default. If you do not want to use the
admin user, then any user you do use must have this capability added to its profile.
To learn more about Splunk users and assigning capabilities, see "About configuring role-based user access" in the core Splunk Enterprise platform documentation.
