Description

When SPNEGO plays up, it's usually deep in something like KMS, WebHDFS, etc.

Given the code is in the JRE, and a simple GET of an endpoint is enough to provoke any problems, KDiag should be able to support a --uri parameter which attempts a GET of the URI, with the diagnostics turned up to 11.
