FreeIPA aims to provide a centrally managed Identity, Policy, and Audit (IPA) system. It uses a combination of Fedora, 389 Directory Server, MIT Kerberos, NTP, DNS, the DogTag certificate system, SSSD and other free/open-source components. FreeIPA includes extensible management interfaces (CLI, Web UI, XMLRPC and JSONRPC API) and Python SDK for the integrated CA, and BIND with a custom plugin for the integrated DNS server. Each of the major components of FreeIPA operates as a preexisting free/open-source project. The bundling of these components into a single manageable suite with a comprehensive management interface is GPLv3, but that does not change the licenses of the components.

The "IPA" part of FreeIPA stands for identity (identifying and authenticating users and machines), policy (settings for access control of applications and machines), and audit (methods for collecting and auditing security events, logs, and user activities).
