SASL/SCRAM servers using the SaslServer implementation included in Kafka must handle NameCallback and ScramCredentialCallback.The username for authentication is provided in NameCallback similar to other mechanisms in the JRE (eg. But, typically, that's not what we'll end up using SASL for, at least in our daily routine. SASL can be enabled individually for each listener. Producers / Consumers help to send / receive message to / from Kafka, SASL is used to provide authentication and SSL for encryption, JAAS config files are used to read kerberos ticket and authenticate as a part of SASL.
