Troubleshooting & FAQ (1)
TroubleshootingHow to use OpenID Connect (OIDC) login with OpenSlides?
OpenSlides does not natively support OIDC yet. As a workaround, deploy a Keycloak instance: configure Keycloak to accept OIDC from your provider (e.g., Pretix), then connect OpenSlides as a SAML client to Keycloak. This bridges OIDC to SAML. Native OIDC consumer support is under development (see PR #6810).
