Hey Athan, I was able to deploy OSX in a samba4 environment. Here is my

go to System Preferences > User and Groups and create a new account with
admin privileges. This will be developed into a default profile for domain
users. Log out and in with the user.

Open Keychain Access and delete "Login"

Spend some time opening all the applications on the operating system,
registering all welcome prompts, and performing all necessary

Go back to System Preferences > User and Groups. Right-click the
appropriate account > Advanced Options: set the Home Directory to

Open a terminal:
sudo rm /Users/[new_default_account]/Library/Caches/*
sudo rm -rf /System/Library/User\ Template/English.lproj/*
cd /System/Library/User\ Template/English.lproj/
sudo rsync -rav /Users/[new_default_account]/ . (that's a period, so you're
copying into the present working directory above)

Apple > Recent items > Clear Menu
Reboot into your normal Admin account.

Delete the account that's been set up.

As Admin, let's bind to the domain controller. Head back to Users and
Groups and head to Login Options.
Edit Network Account Server > Open Directory Utility > Active Directory
Bind to your active directory FQDN.
Under User Experience, uncheck both "Create mobile account at login" and
"Force local home directory on startup disk."

The one other clincher, I think, was going to the ADUC snap-in and mapping
the home directory for all users.
