>             Project: Apache NiFi
>          Issue Type: Bug
>          Components: Core Framework
>    Affects Versions: 0.6.1
>            Reporter: Andy LoPresto

> As discovered in [NIFI-1981], edge cases in configuration of cluster 
> communications over TLS without client authentication caused errors in the 
> application. We should provide a consistent experience, from documentation to 
> configuration to execution:
> * Machine to machine communication should have two settings -- plaintext or 
> TLS with mutual authentication. 
> ** Cluster
> ** Site to Site
> * The API / UI should allow more granular control -- plaintext, TLS with 
> server authentication only, or TLS with mutual authentication. Some clients 
> (API consumers, users in an enterprise environment) may have client 
> certificates, but the majority will not, and TLS authentication of the 
> server, and data integrity and confidentiality assurances should still be 
> available. 
> ** Site to site over the API (see [NIFI-1857]) will respect this setting for 
> the TLS handshake negotiation, but will manually enforce the presence of a 
> client certificate in an HTTP header on any request arriving over HTTPS. 
> The {{nifi.security.needClientAuth}} setting should be removed from 
> nifi.properties. A new setting {{nifi.security.api.needClientAuth}} will be 
> added, and documented to explicitly apply only to the API (and, by extension, 
> Web UI).
