What is SASL method login?

JAAS uses its own configuration file. The recommended location for this file is /opt/kafka/config/jaas.conf.

What is Kerberos SASL?

SASL: Simple Authentication and Security Layer SASL is a mechanism for applications to set up an authenticated communications channel by way of a shared authentication mechanism. Kerberos is one authentication mechanism, but SASL supports others, such as x. 509 certificates.
