Custom OIDC SSO for Bare Metal

Update conf/openmetadata.yaml

Once the Client Id is generated, add the Client Id in openmetadata.yaml file in client_id field.

Update the providerName config to the name you want to display in the Sign In button in the UI. For example, with the following configuration with providerName set to KeyCloak, the users will see Sign In with KeyCloak SSO in the Sign In page of the OpenMetadata UI.

authenticationConfiguration:
  provider: "custom-oidc"
  providerName: "KeyCloak"
  publicKeyUrls:
    - "http://localhost:8080/realms/myrealm/protocol/openid-connect/certs"
    - "{your domain}/api/v1/system/config/jwks" # Update with your Domain and Make sure this "/api/v1/system/config/jwks" is always configured to enable JWT tokens
  authority: "http://localhost:8080/realms/myrealm"
  clientId: "{client id}"
  callbackUrl: "http://localhost:8585/callback"

Then,

  • Update authorizerConfiguration to add login names of the admin users in adminPrincipals section as shown below.
  • Update the principalDomain to your company domain name.
authorizerConfiguration:
  className: "org.openmetadata.service.security.DefaultAuthorizer"
  # JWT Filter
  containerRequestFilter: "org.openmetadata.service.security.JwtFilter"
  adminPrincipals:
    - "user1"
    - "user2"
  principalDomain: "open-metadata.org"

Troubleshooting

  • If you are seeing the below trace in the logs, you need to add the discovery URL
org.pac4j.core.exception.TechnicalException: You must define either the discovery URL or directly the provider metadata

To resolve the error regarding the discovery URL, you need to set the AUTHENTICATION_DISCOVERY_URI in your configuration. This URI is used to discover the OpenID Connect provider's configuration.
