看了下kafka go client, 有如下密码相关配置, 是指这个吗?

		// SASL based authentication with broker. While there are multiple SASL authentication methods
		// the current implementation is limited to plaintext (SASL/PLAIN) authentication
		SASL struct {
			// User is the authentication identity (authcid) to present for
			// SASL/PLAIN or SASL/SCRAM authentication
			User string
			// Password for SASL/PLAIN authentication
			Password string
			// authz id used for SASL/SCRAM authentication

KafkaConfig增加了User和Password两个参数. 但不知Kafka那边如何配置, 未测试.
