Current state: Writing KIP in progress [One of "Under Discussion", "Accepted", "Rejected"]

Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).

Motivation

Default StandardAuthorizer in Kraft mode is defining a KafkaPrincpal as type=User and a name, and a special wildcard eventually.

The difficulty with this solution is that we can't define ACL by group of KafkaPrincipal.

There is a way for the moment to do so by defining RULE to rewrite the KafkaPrincipal name field, BUT, to introduce this way the notion of group, you have to set rules which will make you loose the uniq part of the KafkaPrincipal name of the connected client, and that lost of information for logging later is a problem to identify in a uniq way the client which is connected.

Public Interfaces

Briefly list any new interfaces that will be introduced as part of this proposal or any existing interfaces that will be removed or changed. The purpose of this section is to concisely call out the public contract that will come along with this feature.
