Most of our users find that Samba 4.0 'just works' for them as an AD DC, even replicating to a second DC. > However I'm also interested in how one can handle fail-over.

I would not recommend just rsyncing anything, except the sysvol files. The reason is that rsync will not get a consistent snapshot of the databases. Joining a second DC will be much more seamless. > That's not to say I wouldn't want something better, but that's kind of > the low end of the "acceptable" scale. > > I've done some searches on the list and spent a while looking for > "examples" but I don't easily find any.

The main HOWTO contains information on joining to an existing domain. That is what you need to do on your second DC.
