**Additional context**
Node API is having kafka producer settings with KAFKA_PRINCIPAL_ID. Same machine we are running kinit command with different CACHE_PRINCIPAL_ID to get krb token for different purpose.

When we publish a message to topic it is getting published successfully using the above configuration, but some time it is trying to publish using the CACHE_PRINCIPAL_ID instead of KAFKA_PRINCIPAL_ID and it is getting denied.

I appreciate any help one this.

Start by reproducing the Node API producer configuration on Linux while comparing the configured KAFKA_PRINCIPAL_ID with the CACHE_PRINCIPAL_ID produced by the separate kinit command. Inspect the Kafka producer settings and kinit command together, then determine why publishing sometimes uses the cache principal; done means the cause is identified and publishing consistently uses the intended principal.
