Kibana Authentication Types

With Search Guard, you can choose from several different modes of authenticating users in Kibana.

There are a number of general authentication approaches:

Username/password-based authentication: When using this approach, Search Guard displays a login form where the user enters a username and a password. These credentials are then validated against all Search Guard authentication domains (configured in sg_authc.yml or sg_config.yml). Thus, you can both use the Search Guard internal user database and LDAP to authenticate such users.

Browser-based Single-Sign-On authentication: In this mode, the user is authenticated by a third-party website, like an Identity Provider (IdP) supporting the OIDC or SAML protocol. When an unauthenticated user tries to open Kibana in the web browser, Search Guard will redirect the user to the Identity Provider website, where the user is requested to log in. After successful authentication, the IdP will direct the user back to Kibana and provide cryptographically protected authorization information to Search Guard. As this approach requires web browser interactions, it is only available for Kibana, but not for direct connections to Elasticsearch.

More details: OIDC, SAML

Header-based authentication: This approach is only applicable in very special setups where authentication information is provided as HTTP headers in requests to Kibana. This requires special browser configurations or an additional proxy in front of the Kibana application.
More details: Proxy Authentication (including authentication via JWT Authorization headers), Kerberos

Combining several approaches: All of the approaches can also be used in combination. If several ways of authentication are configured, the Search Guard Kibana plugin will present the user a form to choose the desired authentication mode. It is also possible to run several Kibana instances in front of one Elasticsearch/Search Guard setup using different authentication configurations. More details
