hm. that's odd.
The only thing I could find is
https://github.com/equaeghe/infcloud/blob/master/readme.txt#L72
which currently reads:

    4.) Digest authentication problems and how to solve them (if your server uses digest auth)
        - Why digest authentication is problematic?
          Lot of browsers have wrong or buggy digest auth support (especially if used from JavaScript).
        - What to do to solve this problem?
          a.) Disable the digest authentication and enable the basic authentication in your server config (NOTE: ALWAYS use SSL /https/ for basic authentication!)
          b.) Alternatively (if it is not possible to switch to basic auth) you can try to enable the globalUseJqueryAuth option in config.js (NOTE: there is no guarantee that it will work in your browser)
          NOTE: if you want to use the auth module /see 6.) c.) below/ you MUST use basic auth (there is no digest auth support in this module)!

Unfortunately, it doesn't point to any actually identified problem.
So for now, the claims are not substantiated and it looks as if
theterrible security advice is given without reason.

Sure. But that's two separate issues, as TLS is not used for (client)
authentication. You probably want both, a reasonably secure encryption
as well as a reasonably secure authentication.  Recommending to use the
less secure authentication without (very) good cause seems ill-advised
to me.
