Already that day in a row I have been trying unsuccessfully to configure SASL / SCRAM for Kafka. I am trying to config Spring Cloud Kafka with SASL_SSL but I could not make it works without problems. The SASL/PLAIN binding to LDAP requires a password provided by the client. Listener without any encryption or authentication.
