Hi All,
We would like to go with Option 1, which adds a new configuration parameter
pair of the form:
ssl.principal.mapping.pattern, ssl.principal.mapping.value. This will
fulfill the requirement for most of the common use cases.
We would like to include the KIP in the upcoming release. If there no
concerns, would like to start vote on this KIP.
Thanks,
