Setting server property with underscore in the property name

[shangd]

Hi

I want to set the broker property
listener.name.sasl_ssl.plain.sasl.jaas.config=... (note the underscore in the name)

Using the environment variable KAFKA_LISTENER_NAME_SASL_SSL_PLAIN_SASL_JAAS_CONFIG to set this won't work since it will replace all the underscores.

Is there a way to escape the underscore in the property name?

Not that i'm aware of, as a work around you can just remap sasl_ssl to saslssl and specify the mapping in listener.security.protocol.map as per https://kafka.apache.org/documentation/#configuration (caveat: I haven't tried that, but from what I remember that is the point of the protocol map)
