Secrets & Credentials

Kanidm is a simple and secure identity management platform that offloads authentication and user storage for applications, providing built‑in OAuth2/OIDC, SSH key distribution, RADIUS support, LDAP gateways, CLI tooling, HA, and more.

Rust Latest v1.10.3 · 12d ago Security brief →

Features

  • Passkeys (WebAuthn) with attested high‑security keys
  • OAuth2/OIDC provider for single sign‑on and token exchange
  • SSH key distribution to Linux/Unix hosts
  • RADIUS support for network/VPN authentication
  • Read‑only LDAP gateway for legacy systems

v1.10.1 Breaking risk
⚠ Upgrade required
  • Review the upgrade documentation for steps when removing OpenSSL dependency.
  • If using Kanidm-unixd, consider switching from symlinks to bind mounts for home mapping.
  • Enable account recovery feature via configuration if desired; it requires email sending capability.
Breaking changes
  • OpenSSL is no longer required; all cryptographic paths now use RustCrypto or Rustls (aws-lc-rs).
Security fixes
  • SCIM Filters parsing depth unbounded – fixed high severity Denial of Service (unauthenticated).
  • LDAP Filters parsing depth unbounded – fixed high severity Denial of Service (unauthenticated).
  • PNG Image validation handling short images – fixed moderate severity worker thread panic.
Notable features
  • Account recovery feature allowing users to reset credentials via email and admin‑triggered emails.
  • Kanidm-unixd supports bind mounts as an alternative home mapping strategy.
Full changelog

2026-05-07 - Kanidm 1.10.1 - Patch

  • Resolve an incorrect javascript encoding of some fields that prevents new Webauthn enrolments from completing
  • Correct incorrect text in TOTP CLI credential updates

2026-05-01 - Kanidm 1.10.0

This is the latest stable release of the Kanidm Identity Management project. Every release is the combined effort of our
community and we appreciate their invaluable contributions, comments, questions, feedback and support.

You should review our support documentation as this may have important effects on your distribution or upgrades in
future.

Before upgrading you should review our upgrade documentation

1.10.0 Important Changes

  • OpenSSL is no longer required as a dependency. All cryptographic paths have been replaced by RustCrypto or Rustls using aws-lc-rs.
  • Kanidm-unixd now supports bind mounts as an alternative to symlinks for home mapping.
  • Account recovery can be enabled as a feature allowing a user to prove knowledge of their own email, and then have a credential reset email sent to them.
    • Administrators can also trigger account recovery emails to be sent to users.

1.10.0 Release Highlights

  • Security - High: SCIM Filters did not contain a bound on their parsing depth allowing stack exhaustion to occur leading to Denial of Service by an unauthenticated user
  • Security - High: LDAP Filters did not contain a bound on their parsing depth allowing stack exhaustion to occur leading to Denial of Service by an unauthenticated user
  • Security - Moderate: PNG Image validation did not correctly handle short images allowing a panic to occur in a worker thread. This may lead to system instability over time
  • Security - Low: HTML injection via user DisplayName in Passkey enrolment dialogs. This allows an admin to execute JS in the context of a users browser. Since the admin already can reset the users credentials, the impact of this is minimal.
  • Security - Low: non-constant time comparison of OAuth2 client secret may allow a remote attacker to remotely recovery the bytes of the secret. Due to the length of the secret (48 chars) this is infeasible practically.
  • Security - Low: incorrect handling of origin validation in Webauthn-RS allowed a malicious domain to collide with a valid one (badexample.com would match with example.com). This is mitigated by browsers detecting the forgery and preventing the authentication from proceeding.
  • 20260331 send account recovery emails (#4259)
  • Invert incorrect thread count logic (#4294)
  • Allow modification of OAuth2 Refresh Expiry (#4276)
  • Introspection token auth metadata (#4230)
  • Correctly handle deleted accounts during page visits (#4275)
  • don't fail auth when passed ui_locales (#4288)
  • Feat: Add OIDC Prompt Support (#4224)
  • Handle multivalue URLs in SCIM (#4271)
  • Correctly encode ssh tag values (#4272)
  • Add .well-known/passkey-endpoints (#4255)
  • show repl cert metadata and also handle socket timeouts (#4252)
  • add dependency data to released containers (#4239)
  • cli: allow clearing person's legalname attribute (#4228)
  • OpenSSL shall be vanquished (#4219)
  • add nsswitch config check to unixd (#4210)
  • Added PasswordChangedTime attribute and database field (#3999)
  • Improve FreeBSD building, fully drop ring as a dependency.
  • credential reset emails (authenticated only) (#4151)
  • feat: bind mount home strategy (#3997)
  • Don't revert admin changes in some groups during migrcation (#4176)
  • Alert on unsaved changes (#4155)
  • Warn about systemd-userdb (#4147)
  • Dont token introspection relies on token validity rather than basic auth (#4142)
