# Summary [NIFI-10259](https://issues.apache.org/jira/browse/NIFI-10259) Improves HTTP error handling for authentication failures, providing additional details when the web application rejects a JWT Bearer Token. Improvements include introducing `StandardAuthenticationEntryPoint`, which delegates to the Spring Security `BearerTokenAuthenticationEntryPoint` for OAuth2 Authentication Exceptions. The `BearerTokenAuthenticationEntryPoint` prepares a standard `WWW-Authenticate` HTTP response header containing error parameters described in [RFC 6749 Section 5.2](https://www.rfc-editor.org/rfc/rfc6749.html#section-5.2). The new `StandardAuthenticationEntryPoint` uses the response header as the basis for a response body. For all other Authentication Exceptions, the `StandardAuthenticationEntryPoint` returns an HTTP 401 status code with a response containing a message stating `Unauthorized`. This builds on the current configuration, which returns an HTTP 401 status code without a response body. The `StandardAuthenticationEntryPoint` also checks for the presence of the HTTP Authorization Bearer Cookie, and sets a response header instructing the client to remove the cookie from storage. This implementation follows the strategy in `AccessResource.getAccessStatus()` and provides a more consistent approach. Configuration updates include using the `StandardAuthenticationEntryPoint` as the default Authentication Entry Point for both the Spring Security Filter Chain and the Bearer Token Authentication Filter. # Tracking Please complete the following tracking steps prior to pull request creation. ### Issue Tracking - [X] [Apache NiFi Jira](https://issues.apache.org/jira/browse/NIFI) issue created ### Pull Request Tracking - [X] Pull Request title starts with Apache NiFi Jira issue number, such as `NIFI-00000` - [X] Pull Request commit message starts with Apache NiFi Jira issue number, as such `NIFI-00000` ### Pull Request Formatting - [X] Pull Request based on current revision of the `main` branch - [X] Pull Request refers to a feature branch with one commit containing changes # Verification Please indicate the verification steps performed prior to pull request creation. ### Build - [X] Build completed using `mvn clean install -P contrib-check` - [X] JDK 8 - [ ] JDK 11 - [ ] JDK 17 ### Licensing - [ ] New dependencies are compatible with the [Apache License 2.0](https://apache.org/licenses/LICENSE-2.0) according to the [License Policy](https://www.apache.org/legal/resolved.html) - [ ] New dependencies are documented in applicable `LICENSE` and `NOTICE` files ### Documentation - [ ] Documentation formatting appears as expected in rendered files -- This is an automated message from the Apache Git Service.
