A sovereign, self-hosted identity platform
Microsoft Entra ID and Active Directory alternative, written in Rust
Rumba is under active development. First release planned for Q1 2026.
Rumba is a self-hosted identity platform designed to replace Microsoft Entra ID (Azure AD) and Windows Active Directory. It includes native LDAP and Kerberos server implementations, allowing organizations to run their own identity infrastructure without depending on Microsoft cloud services.
- LDAP Server — Native directory services implementation
- Kerberos KDC — Authentication protocol for Windows and Linux clients
- OAuth 2.0 / OpenID Connect — Identity provider with standard flows
- Microsoft Graph API — Compatibility layer for existing integrations
- Multi-tenant — Multiple organizations from a single deployment
- Linux Integration — NSS/PAM modules for Unix authentication
- Data sovereignty — Identity data stays on your infrastructure
- No vendor lock-in — Independence from cloud provider pricing and policies
- Compliance — Meet data residency requirements for regulated industries
- No subscription fees — One-time deployment, no per-user costs
Homelabs — Run a proper identity infrastructure for your home network. Authenticate Linux and Windows machines, manage users centrally, and learn enterprise identity protocols without cloud dependencies or subscription costs.
Small and Medium Businesses — Deploy identity management that scales with your organization. Avoid per-user licensing, keep data on-premises, and integrate with existing applications through standard protocols.
Regulated Industries — Organizations in healthcare, finance, or government that require data residency or cannot use US-based cloud services.
