generally not. AD is typically setup by a security team somewhere else non-resident to the Tableau server, but accessible within the domain of the network. Tableau should just be able to point at the AD reference via the Tableau admin setup. And you don't need to specify a port for AD, the port on the setup screen is for the Tableau gateway.
Are you providing a proper nickname for your AD pointer? Here is our setup.

AD and Tableau Server don't have to be in the same machine. I would double-check the user name and password.
