Yeah -- this is why I was hoping the "unix password sync" flag would still
It's easy to then set the "passwd program" to point to a wrapper that syncs
Google Apps passwords via their Directory API.
I may end up writing a self-service password manager to invoke both
Google's API and some version of "samba-tool user setpassword"
