Luke Chen commented on KAFKA-16214: ----------------------------------- PR: https://github.com/apache/kafka/pull/15280 > No user info when SASL authentication failure > --------------------------------------------- > > Key: KAFKA-16214 > URL: https://issues.apache.org/jira/browse/KAFKA-16214 > Project: Kafka > Issue Type: Bug > Affects Versions: 3.6.0 > Reporter: Luke Chen > Assignee: Luke Chen > Priority: Major > > When client authenticate failed, the server will log with the client IP > address only. The the IP address sometimes cannot represent a specific user, > especially if there is proxy between client and server. Ex: > {code:java} > INFO [SocketServer listenerType=ZK_BROKER, nodeId=0] Failed authentication > with /127.0.0.1 (channelId=127.0.0.1:9093-127.0.0.1:53223-5) (Authentication > failed: Invalid username or password) > (org.apache.kafka.common.network.Selector) > {code} > If there are many failed authentication log appeared in the server, it'd be > better to identify who is triggering it soon. Adding the client info to the > log is a good start. -- This message was sent by Atlassian Jira (v8.20.10#820010)
