Question : Ports required for domain authentication

Hi,

I wish to add a web server that is on a dmz network, to active directory and the domain which sits across the firewall on another network.

What ports do i need to open to allow this?

is it 53 tcp/udp for joining domains? and 113 tcp/udp for authentication with active directory?

Thanks

Julia
