SSO to Databricks with Keycloak

This article shows how to configure Keycloak as the identity provider for single sign-on (SSO) in your Databricks account. Keycloak supports both OpenID Connect (OIDC) and SAML 2.0. Keycloak does not support SCIM to sync users and groups to Databricks.

Warning

To prevent getting locked out of Databricks during single sign-on testing, Databricks recommends keeping the account console open in a different browser window. You can also configure emergency access with security keys to prevent lockout. See Emergency access to prevent lockouts.
