About kafka sourse with sasl_ss

[yangshike]

this is my vector config：
tls.enabled = true
sasl.enabled = true
sasl.security.protocol = "SASL_SSL"
sasl.mechanism = "PLAIN"
sasl.username = ""
sasl.password = ""

when i run： vector validate -C .

i got error! this is the error info:
2023-02-23T08:37:45.402222Z ERROR rdkafka::client: librdkafka: Global error: SSL (Local: SSL error): sasl_ssl://11.11.11.11：9092/bootstrap: SSL handshake failed: ssl/statem/statem_clnt.c:1919: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed: broker certificate could not be verified, verify that ssl.ca.location is correctly configured or root CA certificates are installed (install ca-certificates package) (after 42ms in state SSL_HANDSHAKE)

The kafka service provider told me that I need to download the certificate, and then configure the certificate on the client. I downloaded the certificate, but I don't know where to put it！！

You will need to set the ssl.ca.location in librdkafka_options.

librdkafka_options."ssl.ca.location" = "/path/to/ca"
