GAPS will not work with a Samba4 DC in the domain. Samba4 doesn't have any
real extendibility in this realm either.
GAPS works by hooking the password change on the DC and then sending the
SHA-1s of the new password to Google. Its important that it's installed on
all DCs because a password change can occur against any writeable DC.
There's another Windows DC solution around that abuses an unused field and
stuffs the SHA-1 in there for sync with GADS. Also not applicable to Samba.
The best approach I have seen is configuring Samba4 to store plaintext
passwords and then sync SHA-1s to Google. For instance:
You could also send the plaintext directly to Google (with Google Apps
Directory Sync), but that's even scarier IMO.
