Can kafka brokers have SASL_SSL, SSL and PLAINTEXT listener at same time?

[Shrinivas Kulkarni]

Hi,

I want to migrate from SSL to SASL_SSL on the Kafka. Is there a way to
enable both SSL and SASL at the same time in a Kafka cluster. Also, I want
PLAINTEXT to be enabled for the internal users. Is this possible in Kafka
1.1.1

Please let me know.

Thanking in anticipation,
Shrinivas
