Does Likewise support Active Directory site awareness for finding local AD resources?
Yes. The Likewise agent locates all the domain controllers and computes the optimal one to use for each computer. This means that the Likewise agent tethers itself to a domain controller in its local site and submits AD requests to that particular domain controller. In the event that the domain controller goes down, the Likewise Unix authentication daemon automatically detects the failure and switches to another domain controller and another global catalog.
