--------------------------------------

[~daryn] - I see no difference between what is provided here and existing 
hadoop.auth cookies for things like webhdfs.

I am assuming that admins are only allowing the use of proxyusers that can be

> Currently KerberosAuthenticationHandler sets the remote user to Knox. Need
