I have a need to use two authentication methods (HTTPS client certs and
username/password) for access to the SVN server. Aside from the additional
security provided by having username/pw on the SVN repo, it is useful to
control authorization permissions by user with a username/pw for each acccount
accessing the repo. Since Hudson uses radio buttons to select the SVN
authentication options, it does not appear to be possible to use both and have
it connect to the SVN repository without removing one of the authentication
measures currently in place.

If there is not a plugin that addresses this case, it would be helpful if
Hudson supported multiple authentication options (or at least those two).
