When Novell ZENworks Network Access Control accesses and tests endpoints, it needs to
know the administrator credentials for that endpoint. If your network uses a Windows
domain controller and the connecting endpoint is a member of a configured domain, Novell
ZENworks Network Access Control uses the information supplied to access and test the
endpoint.
AP
Access Point — The physical point at which an endpoint or device connects to a network.
API
Application Programming Interface — The interface to an application’s source code. Other
computer programs can communicate with the application through this interface.
APIC
