F5OS AD Integration

I'm not usually the person that sets up the AD integration on our hosts.  The person that normally configures it took one look at the new F5OS (1.4) and, well, I won't repeat their comment here.  I figured how hard can it be.  I think I'm reasonably smart and can follow instructions.  I used to think I was resonably smart.  Now I'm not so sure.  I've configured authentication settings and server groups.  Users is still only an option for local.
