I successfully connected my Macbook to my AD domain but I'm not able to login to it using domain credentials. The Mac doesn't have a hard wired connection, only wireless. I've seen this on the Windows side too for tablets and other pc's that don't have wired network connections. For the PCs, I have to connect to the wireless under the local admin account (join the domain) and then switch user (not log off) so that the wireless is still connected to the network and I can log in for the first time to create the profile and cached pwd. I do see the Mac computer account in AD so I think it is bound correctly. If I had a network connection, I think it would work but since it's wireless only (and I don't have a wireless connection at the login screen), it can't see the domain.
