Subject [jira] [Created] (KAFKA-6198) kerberos login fails
Date Fri, 10 Nov 2017 11:57:00 GMT
Ronald van de Kuil created KAFKA-6198:
-----------------------------------------

             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/pi99.dev.ibm.com@DEV.IBM.COM;
authorizationID=kafka/pi99.dev.ibm.com@DEV.IBM.COM. (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:producer@DEV.IBM.COM has Allow permission for operations: Describe from hosts: *
	User:producer@DEV.IBM.COM 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.
[kafka-kerberos-refresh-thread-producer@DEV.IBM.COM] INFO org.apache.kafka.common.security.kerberos.KerberosLogin
- [Principal=producer@DEV.IBM.COM]: TGT refresh thread started.
[kafka-kerberos-refresh-thread-producer@DEV.IBM.COM] INFO org.apache.kafka.common.security.kerberos.KerberosLogin
- [Principal=producer@DEV.IBM.COM]: TGT valid starting at: Fri Nov 10 12:50:11 CET 2017
[kafka-kerberos-refresh-thread-producer@DEV.IBM.COM] INFO org.apache.kafka.common.security.kerberos.KerberosLogin
- [Principal=producer@DEV.IBM.COM]: TGT expires: Fri Nov 10 22:50:11 CET 2017
[kafka-kerberos-refresh-thread-producer@DEV.IBM.COM] INFO org.apache.kafka.common.security.kerberos.KerberosLogin
- [Principal=producer@DEV.IBM.COM]: 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
