Your problem description makes it sound as though what you really want is a multi-master setup (though you don't say why -- it might be possible to more usefully advise you if you tell us why you don't want to use a master/slave setup.)
However, just to clarify the use of terminology in your title question, you asked:
"Can you have multiple authoritative BIND DNS servers for the same zone, like AD-integrated DNS?"
The literal answer to that question is "yes." Slave servers are also authoritative servers for the zones they slave. It doesn't matter that they are not the origin point for new configuration information being added to the zone; the data that is served by slaves is considered authoritative and the AA (Authoritative Answer) flag is set on responses that come from slave servers.
So if your question is actually about authoritative data and you are not accidentally misusing the term to represent another concept, then the answer to your question is actually "yes" and configuration is trivial. I suspect, however, that that's not what you are looking for.
