-Spring Boot 2.x auto-configuration registers an `OAuth2AuthorizedClientManager` `@Bean` in the `ApplicationContext`.
-However, the application may choose to override and register a custom `OAuth2AuthorizedClientManager` `@Bean`.

 The `DefaultOAuth2AuthorizedClientManager` is also associated with a `contextAttributesMapper` of type `Function<OAuth2AuthorizeRequest, Map<String, Object>>`, which is responsible for mapping attribute(s) from the `OAuth2AuthorizeRequest` to a `Map` of attributes to be associated to the `OAuth2AuthorizationContext`.
 This can be useful when you need to supply an `OAuth2AuthorizedClientProvider` with required (supported) attribute(s), eg. the `PasswordOAuth2AuthorizedClientProvider` requires the resource owner's `username` and `password` to be available in `OAuth2AuthorizationContext.getAttributes()`.

 Configuring the `redirect-uri` with `URI` template variables is especially useful when the OAuth 2.0 Client is running behind a <<appendix-proxy-server, Proxy Server>>.
 This ensures that the `X-Forwarded-*` headers are used when expanding the `redirect-uri`.
