External Kafka SASL_SSL is using TLS true

[navneetrajput06]

Hi Team,

When we are using SASL_SSL for external kafka its expecting tls configuration rather it should go pass with SASL user based authentication only. please check the below snapshot and from the link. looks like we need to remove this piece of code.

Below is the kafka configuration. its going good in case of PLAINTEXT but expecting TLS in case of SALS_SSL.

@navneetrajput06 em... correct me if I'm wrong:
SSL is just an old name of TLS see https://www.cloudflare.com/learning/ssl/transport-layer-security-tls/ .
So just as the names suggests,
if you only need SASL, then you can use SASL_PLAINTEXT;
and if you need SASL together with TLS, then you can use SASL_SSL.
