We are using Cisco Clean Access on our network, and are testing for AD authentication on our Macs. With CCA active the Macs can no longer authenticate properly, eventually authenticating after three minutes, but not mounting the desktop properly (local account), and not mounting the network scripted drive/server on the desktop as per usual.

We think this is a port issue and that CCA is not allowing all relevant protocols/ports proper access…

Does anyone have a full list of all protocols and ports needed for a Mac to boot in this situation?
