Issue to load JAAS file on docker-compose

[Fabio Machado]

Hey, guys. How you doing? My name is Fabio and i need a little help.

I need to enable authentication on my kafka broker (using bitnami/kafka
image) using SASL. I've followed the examples of the documentation, but i
got a strange error when i try to up the compose file.
I mounted the jaas file on the correct path on the kafka container (a
simple cat command validating this mounting).
The error is below:
Error: Could not find or load main class
"-Djava.security.auth.login.config=.etc.kafka.kafka_server_jaas.conf" kafka
Caused by: java.lang.ClassNotFoundException:
"-Djava.security.auth.login.config=.etc.kafka.kafka_server_jaas.conf"

My kafka_server_jaas.conf:
#####################
KafkaServer {
  org.apache.kafka.common.security.plain.PlainLoginModule required
  username="admin"
  password="admin-123"
  user_admin="admin123"
  user_user123="user123";
};
Client {};

My entire docker-compose file:
