For our organization the server certificate is considered sensitive and not 
available to the users who need to deploy to NiFi. Actual authentication to 
NiFi is handled through Knox and our SSO Service so the end user never deals 
with SSL or has access to a certificate. Originally I started down the path of 
writing a bunch of tools based on NiPyAPI to handle deployments but since the 
CLI already does that I was hoping to save some work. Currently we do several 
other things via rest using the Kerberos Token.

As I looked through the tool kit CLI I was seeing that auth token being passed 
into all the rest calls so I was hoping I could hijack wherever that was being 
generated via 2way ssl and add an option to call Kerberos instead to get the 
token. When I say token I mean the auth bearer token that you can get from a 
post request to /access/kerberos in NiFi and /access/token/Kerberos in NiFi 
registry.

Thanks

    I meant to say that you obviously could generate certs for CLI users, but I
    was just mentioning an alternative where you can proxy an identity.
    
    Right now the CLI never obtains a token because it is all cert based.
