### Handling authentication ([.kt][AuthenticateKotlin], [.java][AuthenticateJava])

OkHttp can automatically retry unauthenticated requests. When a response is `401 Not Authorized`, an `Authenticator` is asked to supply credentials. Implementations should build a new request that includes the missing credentials. If no credentials are available, return null to skip the retry.

## 0.20.0

* Upgrade OAuth2:
    * Upgrade Password flow using Bearer tokens to use the correct HTTP status code 401 `UNAUTHORIZED`, with `WWW-Authenticate` headers.
    * Update, simplify, and improve all the [security docs](https://fastapi.tiangolo.com/advanced/security/).

		HTTPStatusCode: http.StatusServiceUnavailable,

	ErrUnauthorizedAccess: {
		Code:           "UnauthorizedAccess",
		Description:    "You are not authorized to perform this operation",
		HTTPStatusCode: http.StatusUnauthorized,
	},
	ErrExpressionTooLong: {
		Code:           "ExpressionTooLong",

* To create or update an RBAC RoleBinding or ClusterRoleBinding object, a user must: ([#39383](https://github.com/kubernetes/kubernetes/pull/39383), [@liggitt](https://github.com/liggitt))
     1. Be authorized to make the create or update API request
     2. Be allowed to bind the referenced role, either by already having all of the permissions contained in the referenced role, or by having the "bind" permission on the referenced role.

* `list`/`watch` API requests with a `fieldSelector` that specifies `metadata.name` can now be authorized as requests for an individual named resource ([#63469](https://github.com/kubernetes/kubernetes/pull/63469), [@wojtek-t](https://github.com/wojtek-t))

- Fixed an issue where the `vsphere` cloud provider would not trust a certificate if:
  - The issuer of the certificate was unknown (`x509.UnknownAuthorityError`)
  - The requested name did not match the set of authorized names (`x509.HostnameError`)

* RBAC: the `system:node` role is no longer automatically granted to the `system:nodes` group in new clusters. It is recommended that nodes be authorized using the `Node` authorization mode instead. Installations that wish to continue giving all members of the `system:nodes` group the `system:node` role (which grants broad read access, including all secrets and configmaps) must create an installation-specific...
