Redmine SSO Options in 2026: Community Plugins vs Commercial Support
The landscape in 2026
Self-hosted Redmine still has no built-in SAML or OIDC. Teams typically choose between unmaintained community plugins, a single-purpose commercial auth plugin, or a vendor that only sells SSO with managed hosting. Each path has different support load and long-term risk.
Free community plugins
Several OIDC plugins appeared on redmine.org in 2026. They can work for a technical admin willing to debug IdP quirks, but most lack published compatibility matrices, diagnostics pages, and a maintainer when Redmine 7 ships. SAML forks are often archived or require editing Ruby initializers on the server.
Commercial single-purpose auth
Vendors like RedmineX sell Microsoft Entra auth for roughly €200–300 lifetime. That fits if you only need Entra and want a maintained package. It does not help if you also need Keycloak, Okta, or group sync across projects.
Hosted-only SAML
Some providers offer excellent SAML UX but only on their managed Redmine hosting. That is the wrong trade-off if your compliance requirement is self-hosted data.
RedmineShop approach
We ship a Community edition free forever (OIDC, one IdP, JIT provisioning, admin break-glass) and publish a clear Community vs Pro boundary before selling Pro ($449/year planned) with SAML, group sync, and audit logs. Optional Install Assist ($349) is paid help, not a paywall.
What we recommend
- Need SSO this quarter on self-hosted Redmine? Start with OIDC Community when it GA — or join the waitlist now.
- Need SAML and group sync for compliance? Wait for Pro or budget Install Assist + Community today.
- Evaluating only? Read our SAML checklist and compare your IdP requirements against the Community vs Pro table.
