[Crucible] Request to add support for Kerberized authentication

Hello,

This comes from a support request https://support.atlassian.com/browse/CRC-1832
where we had the following requirement

We are evaluating Crucbile in our company and we find it really useful.
But w.r.t authentication, I find that Crucible supports Basic/Token-based/Trusted application based authentication.
We are skeptical in sending user password across the network in plain text.
Is it possible to use Kerberos authentication or a better way of authenticating for the same?
