HTTP basic authentication provides a simple challenge-and-response process for gaining access to OpenSearch and its resources that prompts you to sign in with a username and password. You enable HTTP basic authentication in the `http_authenticator` section of the configuration by specifying `type` as `basic`, as shown in the following example:

```yml
authc:
basic_internal_auth_domain:
description: "Authenticate using HTTP basic against the internal users database"
http_enabled: true
transport_enabled: true
order: 1
http_authenticator:
type: basic
challenge: true
authentication_backend:
type: internal

http_enabled: true
transport_enabled: true
order: 1
http_authenticator:

authentication_backend:
type: internal
```
Additionally, you can specify the internal user database as the authentication backend by specifying `internal` as the type for `authentication_backend`. See [The internal user database](#the-internal-user-database) for information about this backend.

To use SAML for authentication, you need to configure a respective authentication domain in the `authc` section of `config/opensearch-security/config.yml`. Because SAML works solely on the HTTP layer, you do not need any `authentication_backend` and can set it to `noop`. Place all SAML-specific configuration options in this chapter in the `config` section of the SAML HTTP authenticator:

```yml
authc:
saml_auth_domain:
http_enabled: true
transport_enabled: false
order: 1
http_authenticator:
type: saml
challenge: true
config:
idp:
metadata_file: okta.xml

After you have configured SAML in `config.yml`, you must also [activate it in OpenSearch Dashboards](#opensearch-dashboards-configuration).

We recommend adding at least one other authentication domain, such as LDAP or the internal user database, to support API access to OpenSearch without SAML. For OpenSearch Dashboards and the internal OpenSearch Dashboards server user, you also must add another authentication domain that supports basic authentication. This authentication domain should be placed first in the chain, and the `challenge` flag must be set to `false`:

```yml
authc:
basic_internal_auth_domain:
http_enabled: true
transport_enabled: true
