Hi,

I configured Kafka 0.10.2.1 for SASL/SCRAM by following the documentation [1]. 
But it does work when I use incorrect username or password in the client as 
well. 

I have attached the server.properties, consumer.properties, 
producer.properties, jass config files for broker and client. 

Also, in my producer, I have set        
 {{props.put("sasl.mechanism", "SCRAM-SHA-256");}}

but when running, it shows,
{{kafka.utils.VerifiableProperties  - Property sasl.mechanism is not valid}}

Thanks and Regards,
Menaka
