Kanidm is a self-contained identity management platform written in Rust that provides authentication and authorization services—replacing the need for Keycloak or similar IAM solutions. It natively supports Passkeys (WebAuthn), OAuth2/OIDC, LDAP gateway, RADIUS, SSH key distribution, and Linux/Unix integration with TPM-protected offline authentication, all with strict secure defaults and minimal configuration. Workspace monorepo: server/daemon and server/lib are the identity daemon and core logic; server/testkit provides testing infrastructure; libs/* (crypto, file_permissions, profiles, users, scim_proto) are reusable building blocks; unix_integration/* (pam_kanidm, nss_kanidm, resolver_kanidm) provide system integration; tools/cli is the admin CLI; proto/ holds protocol definitions. Single Cargo.toml coordinates ~20 crates.

System administrators and DevOps engineers deploying identity infrastructure for small teams through enterprises; application developers integrating SSO via OAuth2/OIDC; Linux sysadmins needing WebAuthn-backed SSH authentication; and open-source community contributors who prefer Rust-based, self-hosted identity solutions over proprietary SaaS.

Production-ready and actively maintained: version 1.11.0-dev with comprehensive CI/CD workflows (clippy, rust_build, docker builds, dependency review), multiple deployment targets (Docker via workflows, Kubernetes-ready), and documented release notes. Repo shows steady activity with structured tooling (CLI, testkit, dev containers), indicating mature project governance rather than experimental.

Monorepo complexity: 30+ workspace members spanning server, CLI, PAM/NSS integrations, crypto libs, and SCIM proto—requires careful dependency management. Rust 1.93 MSRV may limit some deployment environments. Single-maintainer risk mitigated by GitHub CODEOWNERS file. Build resource requirements are non-trivial (6GB parallel linking, 6min release build on M1), which can slow CI cycles.

Active development on v1.11.0-dev with automation pipelines for Docker image builds (kanidm, kanidmd, radiusd), JavaScript linting for UI components, Python integration (pykanidm workflow), and automated Dependabot dependency updates. Book documentation actively maintained with individual book workflows. No disabled tag_version workflow suggests semver releases are manual.

Clone: git clone https://github.com/kanidm/kanidm.git && cd kanidm. Install Rust ≥1.93 (via rustup). Build: cargo build --release (~6 min, 6GB RAM). Dev container available: open in VS Code with .devcontainer/devcontainer.json. Run tests: cargo test --workspace.

Add a new authentication mechanism

1. Define the authentication protocol in the design document (book/src/developers/designs/auth.md)
2. Add protocol messages and types to the shared protocol layer (proto)
3. Implement the authentication handler in the core server (referenced in architecture) (book/src/developers/designs/architecture.md)
4. Expose the mechanism through CLI tooling for testing and admin operations (tools/cli)

Integrate Kanidm with a new Unix/Linux distribution

1. Review existing Unix integration architecture (unix_integration/resolver_common)
2. Use PAM module for authentication (unix_integration/pam_kanidm)
3. Use NSS module for user/group resolution (unix_integration/nss_kanidm)
4. Add distribution-specific packaging in build workflows (.github/workflows/rust_build.yml)

Add a new access control policy type

1. Document the new policy model in design documentation (book/src/developers/designs/access_control_defaults.md)
2. Add policy types to the shared protocol definitions (proto)
3. Implement policy evaluation in core (see architecture) (book/src/developers/designs/architecture.md)
4. Add CLI commands for managing the new policy type (tools/cli)

Migrate identities from a legacy IAM system

1. Check if a migration tool already exists for your source system (tools/iam_migrations)
2. If migrating from LDAP, extend the LDAP migration tool (tools/iam_migrations/ldap)
3. If migrating from FreeIPA, use the FreeIPA migration tool (tools/iam_migrations/freeipa)
4. Use the CLI tool to verify migrated identities (tools/cli)

• Rust (MSRV 1.93, Edition 2021) — Memory safety for identity management code without garbage collection; strong type system prevents authentication logic errors; ideal for Unix system integration (PAM, NSS modules)
• Workspace structure with multiple crates — Enables modular components (CLI, PAM, NSS, migrations) while sharing core protocol and abstractions; reduces cross-cutting concerns and allows independent versioning
• WebAuthn/Passkeys — Cryptographically secure authentication without passwords; aligns with modern identity standards and FIDO2 compliance
• OAuth2/OIDC — Industry-standard token-based authentication for SSO and service-to-service authentication; enables integration with existing applications
• Linux/Unix PAM & NSS modules — Seamless integration with existing Unix authentication stacks without requiring system-level code changes

• Single monolithic identity backend vs. federated providers

  • Why: Kanidm aims to be self-contained; integrating with external providers adds complexity but improves flexibility
  • Consequence: Simpler deployment for small organizations, but enterprises may need federation bridges (not in core scope)

• Strict default security posture with self-healing components

  • Why: Reduces misconfiguration risks in production deployments
  • Consequence: Initial setup may feel restrictive; configuration requires understanding security implications

• Complete identity provider (including OAuth2/OIDC, WebAuthn, application portal) vs. minimal core

  • Why: Reduces external dependencies and integration complexity for end users
  • Consequence: Larger codebase with broader scope; more surface area for vulnerabilities

• Support for legacy SAML 1.0/1.1 authentication protocols
• Real-time multi-tenancy within a single Kanidm instance (single tenant design)
• Built-in application gateway or reverse proxy functionality
• Direct integration with proprietary identity vendors (Microsoft Entra, Okta) as primary backend
• Platform-specific support beyond Linux/Unix (Windows/macOS integrations deferred)

Workspace complexity: cargo build -p server_daemon targets the daemon specifically, but test files scattered across lib/daemon/testkit crates—run full cargo test --workspace for safety. Release profile tuning (thin LTO, 32 codegen-units) must be preserved to avoid OOM on machines <8GB. NSS/PAM integration is system-level code—modifying unix_integration/* requires knowledge of GLIBC/PAM plugin ABI, not just Rust. MSRV is Rust 1.93; older toolchains will fail. LDAP gateway is read-only by design—write operations fail silently; check server/lib tests for expected behavior.

• WebAuthn / FIDO2 Passkeys — Kanidm's flagship auth method (mentioned as primary in README); cryptographically stronger than passwords, replaces TOTP; implemented in libs/crypto and core server logic
• OAuth2 / OIDC (OpenID Connect) — Kanidm is an OAuth2/OIDC provider enabling SSO for external applications; core capability for application portal and token exchange
• LDAP Gateway (Read-Only) — Kanidm proxies LDAP queries to legacy systems without requiring native Kanidm clients; architectural bridge pattern for backward compatibility
• RADIUS Protocol — Network/VPN authentication in Kanidm; separate radiusd binary allows NAS (network access server) integration without modifying core daemon
• PAM (Pluggable Authentication Modules) — Linux system authentication integration via pam_kanidm; allows Kanidm to act as identity provider for UNIX login without modifying system binaries
• NSS (Name Service Switch) — UNIX user/group resolution layer (nss_kanidm plugin); decouples identity backend from GLIBC, enabling seamless Kanidm user enumeration
• TPM-Protected Offline Authentication — Linux clients cache authentication material in TPM 2.0; enables login when server is unreachable while maintaining security

• keycloak/keycloak — Direct competitor in IAM space; Java-based, more heavyweight; Kanidm positions as simpler, Rust-native alternative
• zitadel/zitadel — Modern Go-based IAM with OAuth2/OIDC; similar feature set to Kanidm but different language/deployment model
• ory/kratos — Focused identity & user management API; often paired with Ory Hydra (OAuth2); Kanidm is all-in-one alternative
• openldap/openldap — Traditional LDAP server; Kanidm includes read-only LDAP gateway for legacy system compatibility, building on LDAP concepts
• pykanidm/pykanidm — Python client library for Kanidm (tracked in CI workflow pykanidm.yml); ecosystem companion for Python-based integrations

Add comprehensive CI workflow for Python pykanidm package

The repo has a .github/workflows/pykanidm.yml workflow file listed, but there's no corresponding Python package directory visible in the file structure. This suggests either incomplete Python integration testing or missing documentation. A new contributor could create a dedicated Python package with proper unit tests, type hints, and a complete CI pipeline that tests against multiple Python versions (3.9+), runs mypy/pylint checks, and validates package publishing to PyPI.

• [ ] Create libs/pykanidm/ directory structure mirroring the Rust client library structure
• [ ] Implement comprehensive unit tests covering Kanidm API client operations
• [ ] Add .github/workflows/pykanidm.yml enhancements to test against Python 3.9, 3.10, 3.11, 3.12
• [ ] Add type checking with mypy to the Python CI workflow
• [ ] Document the Python client library in book/src/ with usage examples

Add Windows-specific integration tests for PAM/NSS modules

The repo has .github/workflows/windows_build.yml but the unix_integration/ directory structure suggests PAM and NSS modules that are Unix-specific. A new contributor could create Windows-compatible alternatives or add comprehensive testing that validates the build doesn't break on Windows while documenting platform-specific limitations. Currently there's no visibility into what the windows_build.yml actually tests.

• [ ] Audit .github/workflows/windows_build.yml to document current Windows build scope
• [ ] Add Windows-specific tests for any cross-platform components in libs/
• [ ] Create documentation in book/src/ explaining platform support matrix for each component
• [ ] Add integration tests validating Windows build doesn't regress unix-specific features

Implement missing device_flow OAuth2 integration tests and documentation

The tools/device_flow/ module exists but has no visible test coverage in the file structure, and the README only partially documents Kanidm features. Device flow is a critical OAuth2 pattern for CLI and headless applications. A new contributor could add comprehensive integration tests for the device flow implementation and add a dedicated documentation section to book/src/ with examples for different client types.

• [ ] Create tools/device_flow/tests/ with unit tests for token exchange, polling, and error scenarios
• [ ] Add integration tests in server/testkit validating device flow against a test Kanidm instance
• [ ] Document device flow in book/src/ with examples for CLI clients, scripts, and desktop applications
• [ ] Add clippy and coverage checks for device_flow to .github/workflows/clippy.yml

• Add integration tests for OAuth2/OIDC token exchange flow in server/testkit/—currently testkit-macros provide scaffolding but token endpoint validation tests are minimal
• Document system integration setup in book/src/—UNIX integration (PAM/NSS/resolver) lacks step-by-step configuration guide for admin users; add examples for Debian/RHEL
• Expand CLI help text in tools/cli/src/—many sub-commands (user add, group modify, policy set) lack examples; add --example or -E flags showing common workflows

Kanidm demonstrates a generally strong security posture as an identity management platform with coordinated disclosure policy and security contact procedures. However, there are several areas requiring attention: (1) Potential MSRV configuration issue that could allow outdated compiler versions, (2) Incomplete SECURITY.md documentation, (3) The complexity of Unix system integration (PAM/NSS) requires

• Medium · Rust Version Constraint May Allow Outdated Compiler — Cargo.toml - workspace.package.rust-version. The workspace configuration specifies rust-version = '1.93', which appears to be a future or non-existent version. This could indicate a configuration error or allow builds with significantly older Rust versions that may contain known security vulnerabilities. The MSRV (Minimum Supported Rust Version) should be carefully managed. Fix: Verify the intended MSRV value. Use a documented, released Rust version (e.g., 1.75 or 1.80). Ensure CI/CD pipelines explicitly test against this version and that security advisories for that compiler version are monitored.
• Low · LTO Configuration May Impact Security Analysis — Cargo.toml - profile.release.lto. The release profile uses 'thin' LTO (Link Time Optimization) instead of 'fat' or full LTO. While 'thin' LTO provides faster builds, 'fat' LTO enables more aggressive optimization passes that could potentially catch and optimize away certain classes of vulnerabilities. This is a minor concern for a security-focused project. Fix: Consider evaluating 'fat' LTO for release builds if build time permits, particularly for security-critical components. Document the tradeoff between build time and optimization thoroughness.
• Low · Debug Symbols Enabled in Release Build — Cargo.toml - profile.release.debug. The release profile has debug = true, which includes debug symbols in the release binary. While useful for debugging and crash analysis, this can expose more information about the binary structure and potentially aid reverse engineering or vulnerability research. Fix: Evaluate the operational requirements for debug symbols. Consider using separate debug and release profiles if debug information should not be shipped in production binaries. Ensure binaries are stripped during final deployment if debug symbols are not needed.
• Medium · Incomplete Security Policy Documentation — SECURITY.md. The SECURITY.md file appears truncated in the provided content. Security policies should be complete, clear, and include details about supported versions, security update timelines, and full contact procedures. Fix: Ensure the security policy is complete and publicly visible. Include: supported versions, patch timelines, version deprecation schedule, and clear disclosure procedures. Verify the email addresses are actively monitored.
• Low · Multiple Building Block Dependencies Increase Surface Area — Cargo.toml - workspace.members. The workspace includes 23 member crates spanning CLI tools, Unix integration modules (NSS, PAM, resolver), protocol buffers, and cryptographic libraries. Each introduces transitive dependencies that must be monitored for vulnerabilities. Fix: Implement automated dependency scanning with tools like 'cargo-audit' and 'cargo-deny' in CI/CD. Maintain a vulnerability response plan for transitive dependencies. Consider using 'cargo-supply-chain' to audit publisher trustworthiness.
• Medium · Unix Integration Modules (PAM/NSS) Require Extra Security Scrutiny — unix_integration/pam_kanidm, unix_integration/nss_kanidm. The presence of PAM and NSS modules suggests system-level integration. These components run with elevated privileges and handle authentication flows. Any vulnerabilities here could compromise system security. Fix: Implement rigorous security testing for PAM/NSS modules including: input validation testing, privilege escalation testing, and integration tests with actual system libraries. Consider external security audits for these components.
• Low · Cryptographic Library Requires Regular Updates — libs/crypto. The workspace includes a custom crypto library (libs/crypto). Custom cryptographic implementations are high-risk and must be maintained to the highest security standards. Fix: Ensure the cryptographic library: uses well-vetted algorithms, has undergone professional security audit, is regularly updated for any discovered weaknesses, and has comprehensive test coverage. Consider using established crates (ring, sodiumoxide) where possible rather than custom implementations.
