I see that we can specify username and password in the output Kafka of Filebeat but these fields are not present in the Kafka output of Logstash. What can I do to specify username and password ?

The exemple of input in Filebeat :

> output.kafka:  
> enabled: true  
> hosts: ["\<Kafka\_Broker\_1\>:", "\<Kafka\_Broker\_2\>:"]  
> topic: 'NAME'  
> username: "user"  
> password: "mdp"  
> ssl.endpoint: "https"  
> required\_acks: 1  
> compression: gzip

I think it is going to be something like

```
sasl_mechanism => "PLAIN"
sasl_jaas_config => "org.apache.kafka.common.security.plain.PlainLoginModule required username='username' password='password';"

```
