Subject Re: NiFi Toolkit CLI Token Creation
Date Thu, 13 Jun 2019 17:00:48 GMT
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
Shawn

    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.
