Splunk with an Enterprise license comes with Splunk's built-in authentication enabled by default. Splunk's authentication allows you to add users, assign them to roles, and give those roles custom permissions as needed for your organization.
If your enterprise uses LDAP and you'd like to use the users and groups defined there instead of Splunk's authentication, you can use that instead.
