Subject: RE: Is there any patch to crack MySQL Network auth?
This code is now in magnum-jumbo (jumbo-unstable tree), and needs to be
pushed into magnum-bleeding. This was a rather large amount of code
change. It was my belief that we were locking down j6-fixes tree (jumbo-7)
to fixes, so the code has not been targeted to that build. But the ability
to do things like 'raw' multiple crypts on the larger hashes within dynamic
is now possible.
Jim.
