------------------------------------------------------------------------
The following example shows how you can do preemptive spnego login with HTTP
client that uses a custom entry in the {{login.conf}}. This completely bypasses
the AuthScheme stuff and does all the work of generating the "authorization"
header. So you will notice the example is just a simple minimal http client
with a single header on the httpget request doing all the authentication work.
{code}
... working on a better version below ...
{code}
Might be worth trying to find some way to get this as a supported auth scheme
type, or add this example to the docs.

> you need to specify system properties to specify a custom krb5.conf or
> login.conf location.
> It would be very useful if these could be given as parameters somehow instead
> of system properties, because in our cloud apps use case, sharing these as
> system properties at the jvm level is causing conflicts.
