------------------------------------
Summary: Custom Principal Builders Can't Access SslPrincipalMapper
Key: KAFKA-15452
URL: https://issues.apache.org/jira/browse/KAFKA-15452
Project: Kafka
Issue Type: Bug
Affects Versions: 2.8.1
Reporter: Raghu Baddam
When We are Implementing a Custom KafkaPrincipalBuilder, we don't have access
to SslPrincipalMapper and also kerberosShortNamer.
Without SslPrincipalMapper, the Custom KafkaPrincipalBuilder can't parse the
Regex Rules from the BrokerSecurityConfigs.SSL_PRINCIPAL_MAPPING_RULES_CONFIG
that results in not supporting Mapping Rules because SslPrincipalMapper will be
null.
In our case I have found a workarounds to read config and build my another
SslPrincipalMapper but I think It should be handled at the ChannelBuilders or
SslChannelBuilder itself.
Git Reference:
[https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/network/ChannelBuilders.java#L223-L242]
If Community believe that it is a bug then I am happy to come up with a fix.
