dengziming commented on KAFKA-13859: ------------------------------------ [~opayne] Do you have more detailed exception stack trace, that would be useful? whether ClusterAuthorizationException is got from clients or broker log? > SCRAM authentication issues with kafka-clients 3.0.1 > ---------------------------------------------------- > > Key: KAFKA-13859 > URL: https://issues.apache.org/jira/browse/KAFKA-13859 > Project: Kafka > Issue Type: Bug > Components: clients > Affects Versions: 3.0.1 > Reporter: Oliver Payne > Priority: Major > > When attempting to produce records to Kafka using a client configured with > SCRAM authentication, the authentication is being rejected, and the following > exception is thrown: > {{org.apache.kafka.common.errors.ClusterAuthorizationException: Cluster > authorization failed.}} > I am seeing this happen with a Springboot service that was recently upgraded > to 2.6.5. After looking into this, I learned that Springboot moved to > kafka-clients 3.0.1 from 3.0.0 in that version. And sure enough, downgrading > to kafka-clients resolved the issue, with no changes made to the configs. > I have also attempted to connect to a separate server with kafka-clients > 3.0.1, using plaintext authentication. That works fine. So the issue appears > to be with SCRAM authentication. > I will note that I am attempting to connect to an AWS MSK instance. We use > SCRAM-SHA-512 as our sasl mechanism, using the basic {{ScramLoginModule.}} -- This message was sent by Atlassian Jira (v8.20.7#820007)
