Login module not specified in JAAS config - kafka-manager-1.3.3.21

Hi

I am running Kafka with SASL_PLAINTEXT. I have configed Kafka-manager to use this and provided a jaas file with the correct options (well options that work for all other consumers) - but when starting kafka-manager I get the error “Login module not specified in JAAS config”

The consumers & offsets are not visible in the UI.

version kafka-manager-1.3.3.21

jaas file:

KafkaClient {
   com.sun.security.auth.module.Krb5LoginModule required
   useKeyTab=true
   keyTab="/etc/security/keytabs/kafka.service.keytab"
   storeKey=true
   useTicketCache=false
   serviceName="kafka"
   principal="XXXXXXX";
};

Hi,

I was having the same problem, but I managed to resolve the error, at least in my config.

Basically the JAAS Config from the UI expect a JAAS file content (KafkaClient Section), not a path to the jaas file.

[tanuj83]

it is not working for me, can any one please provide complete steps?
