Bart Van Bos created KAFKA-14340: ------------------------------------ Summary: KIP-880: X509 SAN based SPIFFE URI ACL within mTLS Client Certificates Key: KAFKA-14340 URL: https://issues.apache.org/jira/browse/KAFKA-14340 Project: Kafka Issue Type: Wish Components: security Affects Versions: 3.3.1 Reporter: Bart Van Bos
Istio and other SPIFFE based systems use clients certificates to provide workload ID. Kafka currently does support Client Cert based AuthN/Z and mapping to ACL, but only so be inspecting the CN field within a Client Certificate. There are several POC implementations our there implementing a bespoke _KafkaPrincipalBuilder_ implementation for this purpose. Two examples include * [https://github.com/traiana/kafka-spiffe-principal] * [https://github.com/boeboe/kafka-istio-principal-builder] (written by myself) This KIP request is to include this functionality into Kafka's main functionality so end-users don't need to load custom and non-vetted java classes. The main use case for me is having a lot of istio customers that express the will to be able to leverage SPIFFE based IDs for there Kafka ACL Authorization. -- This message was sent by Atlassian Jira (v8.20.10#820010)
