> In a secure environment, with kerberos, when the KMSClientProvider instance is created
in the context of a proxied user, The initial SPNEGO handshake is made with the currentUser
(the proxied user) as the Principal.. this will fail, since the proxied user is not logged
in.
> The handshake must be done using the real user.
