Nesta exceção, nós incluímos os escopos necessários (se houver algum) como uma string separada por espaços (utilizando `scope_str`). Nós colocamos esta string contendo os escopos no cabeçalho `WWW-Authenticate` (isso é parte da especificação).

**Note that by default no policy is set on a user**. Thus even if they successfully authenticate with AD/LDAP credentials, they have no access to object storage as the default access policy is to deny all access.

 *  **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.

  - `alpha` support (guarded by the `ServiceAccountTokenPodNodeInfo` feature gate) for including the node name (and uid, if the node exists) as additional claims in service account tokens it issues which are bound to pods, and `authentication.kubernetes.io/node-name` and `authentication.kubernetes.io/node-uid` extra user info when the token is used to authenticate.

* Fixes request header authenticator by presenting the request header client CA so that the front proxy will authenticate using its client certificate. ([#40301](https://github.com/kubernetes/kubernetes/pull/40301), [@deads2k](https://github.com/deads2k))
