    Add section on configuring protected auth paths

    Without this change, the federation guide does not do a good job of
    explaining which URL paths should be protected by a federation-capable
    auth module and why. Instead, the SP-specific guides give code samples
    with no context, which makes it confusing to understand how to modify
    the paths in the examples to fit one's own deployment. This change adds
    that introduction.
