TGS request result: Server not found in Kerberos database

[shrimallepudi]

I'm using librdkafka 1.8.2 with confluent-kafka 1.8.2. I've configured my kafka producer as below:

'bootstrap.servers': ,
'client.id': socket.gethostname(),
'debug': 'security,broker',
'security.protocol': 'SASL_PLAINTEXT',
'sasl.kerberos.service.name': <service_name>,
'sasl.kerberos.principal': <principal_id>,
'sasl.mechanism': 'GSSAPI',
'sasl.kerberos.keytab': <kt_file>,
'sasl.kerberos.kinit.cmd': 'kinit -R -t "%{sasl.kerberos.keytab}" -k %{sasl.kerberos.principal} || kinit -t "%{sasl.kerberos.keytab}" -k %{sasl.kerberos.principal}',
'enable.auto.commit': True

When I run my python producer script, it throws error saying 'TGS request result: -XXXXX/Server not found in Kerberos database'. Can someone please let me know what's wrong? I'm using Python 3.6

PS: I'm able to publish messages to the clusters/brokers via console-producer.sh.

There is something wrong with your Kerberos configuration options. Check that kinit works with the parameters shown.

[shrimallepudi]

I understand. I'm sure that we have all the necessary gssapi/sasl packages installed, but still, a validation would always be helpful. Could you please list down the libraries/packages I need to get installed on our servers?

[rolandyoung]

When you raised this issue, you deleted the checklist that says "IMPORTANT: We will close issues where the checklist has not been completed." Please fill that out.
Having said that, you would probably get a different error if you had a library missing. That error indicates that the correct library is being invoked, but it is unable to obtain the required ticket.

This was actually raised as a discussion thread rather than an issue, which is why I didn't see any option to add checklist. Where do I need to do that?

[rolandyoung]

Sorry, my mistake. To see the checklist, you could start to raise an issue but close the browser tab before actually doing so. I'm sorry, but I am going to have to leave this thread alone now. I'm not a librdkafka maintainer, but I recognised a Kerberos error and tried to help by checking that you had done the kinit / klist checks.

Thank you for stepping in, Roland. I appreciate it :)
