Alice needs to be able to produce to topic test using the Produce API. The generic ACL statement at the start of this article achieves this purpose. For more details on the cf CLI, see the documentation. Let’s get started. All associations can be found in the source code: There are hands-on articles that talk about how to use Kafka ACLs (e.g. In this section, you use this generic statement to provide the necessary access to users alice, bob, and charlie. We have seen the similar authentication examplewithout using Spring framework. All organizations struggle with their data due to the sheer variety of data types and ways that it can, Organizations define standards and policies around the usage of data to ensure the following: Data quality: Data streams follow the defined data standards as represented in schemas Data evolvability: Schemas, Due to the distributed architecture of Apache Kafka®, the operational burden of managing it can quickly become a limiting factor on adoption and developer agility. the custom login module that is used for user authentication. Bob’s ACL for fetching from topic test is: Bob needs a second ACL for committing offsets to group bob-group (using the OffsetCommit API): By granting these permissions to Bob, he can now consume messages from topic test as a member of bob-group. In this tutorial, we will learn about securing our spring boot application with spring security role-based LDAP authentication. Using Spring Boot Auto Configuration. Lastly, user charlie needs permission to retrieve committed offsets from group bob-group (using the OffsetFetch API). This is covered in the next section. When the form is submitted it’s automatically validated and errors are available in the BindingResult. And finally, from the “credit-where-credit-is-due” department, much thanks to Sridhar Vennela from Pivotal for his support. The use case involves users alice, bob, and charlie where: So far, the broker is configured for authenticated access. It also provides the option to override the default configuration through application.properties. To secure these APIs, other means can be put in place (e.g., network firewalls) to ensure anonymous users cannot make changes to Kafka topics or Kafka ACLs. We will apply two approaches to publish our endpoint using Apache CXF Spring Boot starter or JAX-WS Spring API.
