Hi Tao, I have a couple of questions:
1. Is there a reason why you wouldn't want to implement a custom SASL mechanism to use your authentication mechanism? SASL itself aims to provide pluggable authentication mechanisms. 2. The KIP suggests that you are interested in plugging in a custom authenticator, but not a custom transport layer. If that is the case, maybe you need CUSTOM_PLAINTEXT and CUSTOM_SSL for consistency with the other security protocols (which are a combination of transport layer protocol and authentication protocol)?
