 * OAuth, SPNEGO, or other authentication mechanisms. Each authenticator is responsible
 * for obtaining login credentials, resolving user information, and managing SSO

 * <p>This authenticator enables Single Sign-On (SSO) using SAML 2.0 protocol
 * with Identity Providers such as Okta, Azure AD, OneLogin, etc.</p>
 *
 * <h2>Required Configuration</h2>

If the response issues an authorization challenge, OkHttp will ask the [`Authenticator`](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-authenticator/) (if one is configured) to satisfy the challenge. If the authenticator supplies a credential, the request is retried with that credential included.

## Retrying Requests

    ones that are no longer necessary.

 *  **OkHttp no longer uses the global `java.net.Authenticator` by default.**
    We've changed our `Authenticator` interface to authenticate web and proxy
    authentication failures through a single method. An adapter for the old
    authenticator is available in the `okhttp-urlconnection` module.
