-------------------------------
Summary: Clarify usage of `Principal` in the authentication layer (was:
Clarify usage of `Principal` at the authentication layer)
> Clarify usage of `Principal` in the authentication layer

> Key: KAFKA-2858
> URL: https://issues.apache.org/jira/browse/KAFKA-2858
> Project: Kafka
> Issue Type: Improvement
> Components: security
> Reporter: Ismael Juma
> Assignee: Ismael Juma
> Priority: Minor
>
> We currently use `KafkaPrincipal` at the authentication and authorization
> layer. But there is an implicit assumption that we always use a
> `KafkaPrincipal` with principalType == USER_TYPE as we ignore the the
> principalType of the `KafkaPrincipal` when we create `RequestChannel.Session`.
> I think it would be clearer if we used a separate `Principal` implementation
> in the authentication layer.
