Yes. The mechListMIC change is less dependent on synchronization
between versions. We can change that in either place and it shouldn't
break anything.

The sec=mskrb5 change is not as forgiving. A new kernel + and older
upcall program will not work if the server sends the MSKRB5 OID first.
This is the reason that I don't want to back out that patch. It would
have been nice to have that patch make samba 3.2.2, but it looks like
we missed it...

Igor, I'll plan to respin the kernel patches if you want to concentrate
on the userspace piece. I should be able to get something ready by
Thursday sometime...
