---------------------------------
Summary: Custom KafkaPrincipalBuilder Cannot Access SslPrincipalMapper
(was: Custom Principal Builders Can't Access SslPrincipalMapper)
> Custom KafkaPrincipalBuilder Cannot 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
> Priority: Minor
> Labels: kafka, walmart
>
> 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.
