Kanidm is an identity management platform designed to simplify authentication and identity storage for various applications. It aims to be a comprehensive identity provider, eliminating the need for additional components like Keycloak. Kanidm is built for diverse use cases, from small home labs to large enterprises, thanks to its focus on strict defaults and user-friendly configuration. Key features include support for passkeys, OAuth2/OIDC authentication, Linux/Unix integration, RADIUS for network authentication, and a self-service WebUI. Compared to similar projects, Kanidm offers a broader feature set. For instance, LLDAP is simpler but requires external portals like Keycloak for OAuth2 support. Kanidm provides these features natively. In contrast to 389-ds and OpenLDAP, which require additional components for identity management, Kanidm integrates these capabilities seamlessly. It outperforms FreeIPA in speed, with tests showing it handles search operations up to three times faster and modifications five times faster, while maintaining a lighter resource footprint. Kanidm also differentiates itself from other IDM providers like Keycloak, Rauthy, and Authelia by offering more robust support for Unix authentication and advanced authentication policies without relying on external SQL databases, reducing potential performance issues. For those interested in contributing, Kanidm welcomes developers of all backgrounds and provides resources to get started.
