Joining the CalNetAD forest offers several advantages to system administrators and computer users. CalNetAD is already integrated with campus infrastructure for DNS and CalNet authentication. CalNetAD provides support for a single sign-on environment and improved security at the desktop level. If you join as an Organization Unit, your Active Directory information will be included in the centralized support for the hardware, security, and backup provided to the central domain controllers. Active Directory can also help system administrators with software distribution and easier control of Windows-based computers via Group Policy Objects.
