Yes, your approach to passing the keytab and principal in the

sasl.jaas.config

field of the consumer properties is generally correct. However, you need to escape the double quotes around the file path and principal name in the

sasl.jaas.config

value. Use

\"

instead of

"

. Also, ensure your Kerberos and Kafka configurations are correct and compatible with Druid version 28.0.0. If you're still facing issues, check Druid and Kafka logs for more detailed error messages.

Hi @Tim Wolfe, I did try using

\"

but was still facing errors. Please check the below thread. I have mentioned the druid error log. https://apachedruidworkspace.slack.com/archives/C0309C9L90D/p1708491736733899
