Update conf/openmetadata.yaml

Once the Client Id and Client Secret are 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"
  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.catalog.security.DefaultAuthorizer"
  # JWT Filter
  containerRequestFilter: "org.openmetadata.catalog.security.JwtFilter"
  adminPrincipals:
    - "user1"
    - "user2"
  botPrincipals:
    - "ingestion-bot"
  principalDomain: "open-metadata.org"

  password: ${AIRFLOW_PASSWORD:-admin}
  metadataApiEndpoint: ${SERVER_HOST_API_URL:-http://localhost:8585/api}
