The way they've worded this very much makes it sound as though patches
are not forthcoming.

Is this a design flaw, or an oversight in the implementation?

If the former, why is it that other vendors (e.g. IBM) are releasing
patches claiming to fix the problem? And, if the latter, is Sun
*really* saying "instead of fixing the problem, we're going to tell all
of our customers to use DES authentication, and if they can't or won't,
then to hell with them"?

(Anyone know any decent references for setting up Secure RPC under
Solaris, particularly if NIS or NIS+ is not in use?)
