Macs + AD = ?

I know — its scary. I’m trying to get an OS X machine connected and running under our Microsoft AD. I’ve found a number of useful instructions while googling around — but nothing seems to work. I think that its due to encrypted SMB (due to the GPO) but after changing that it still doesn’t work.

I hate mac’s, and I hate AD’s more. Why cant someone come up with a good centralized login system that ALL OS’s can use and support nativly (not this hacked crap).
