Ports required for Lync and Active Directory

Dear All,

I’m going to implement Lync 2013 environment in my network, as per the security rules, Lync servers will be installed in a dedicated VLAN which nothing on it, so the active directory domain controllers are not in the same VLAN with Lync.

I need to ask what are the ports I have to open between Lync and DC’s?

I check all the below links but I couldn’t find it:

I think Microsoft wouldn't recommend installing Lync on a different vlan than the one AD is installed on!

But generally if you have DNS on the DC then Lync will talk DNS port and LDAP 3268/389 TCP.  

check out these two references.
