-----------------------------------------
Summary: kerberos login fails
Key: KAFKA-6198
URL: https://issues.apache.org/jira/browse/KAFKA-6198
Project: Kafka
Issue Type: Test
Components: clients
Affects Versions: 0.11.0.1
Environment: raspberrypi
Reporter: Ronald van de Kuil
Priority: Minor
I got very far with setting up kerberos on the raspberry pi as part of self
study.
I believe that the kafka server is happy with kerberos:
[2017-11-10 12:17:51,659] INFO Successfully authenticated client:
authenticationID=kafka/[email protected];
authorizationID=kafka/[email protected].
(org.apache.kafka.common.security.authenticator.SaslServerCallbackHandler)
[2017-11-10 12:17:51,661] INFO Setting authorizedID: kafka
(org.apache.kafka.common.security.authenticator.SaslServerCallbackHandler)
I have setup the kafka.security.auth.SimpleAclAuthorizer
And granted the following access:
Current ACLs for resource `Topic:kerberos-topic`:
User:producer has Allow permission for operations: Describe from hosts:
*
User:producer has Allow permission for operations: Write from hosts: *
User:[email protected] has Allow permission for operations: Describe
from hosts: *
User:[email protected] has Allow permission for operations: Write
from hosts: *
When I start the client, then I see it getting the kerberos ticket:
[main] INFO org.apache.kafka.common.security.authenticator.AbstractLogin -
Successfully logged in.
[[email protected]] INFO
org.apache.kafka.common.security.kerberos.KerberosLogin -
[[email protected]]: TGT refresh thread started.

[[email protected]] INFO
org.apache.kafka.common.security.kerberos.KerberosLogin -
[[email protected]]: TGT refresh sleeping until: Fri Nov 10
21:13:37 CET 2017
But the client fails to login:
[kafka-producer-network-thread | producer-1] WARN
org.apache.kafka.clients.NetworkClient - Connection to node -1 terminated
during authentication. This may indicate that authentication failed due to
invalid credentials.
I do not see any warnings in the logs, so I do not have much to go on.
What can I do to get my finger behind this issue?
Thank you,
Ronald - the NOOB
