ADmitMac v3 allows Macintosh users running Mac OS X 10.3 Panther, or Mac OS X 10.4 Tiger (with the latest updates), to participate in and take advantage of all the directory services provided by Microsoft's Active Directory, NT, and Apple's Workgroup Manager. As a result, administrators can manage their domain users consistently regardless of which operating system they use. ADmitMac allows Macintosh access based on domain credentials and provides support for local or network home folders.

ADmitMac is tailored for multi-user, multi-computer scenarios with administrator defined network security. It supports the highest levels of security and does not require the downgrading of security when using Windows Server 2003. Kerberos is used to provide secure directory access, thus reducing the risk of unwanted disclosure, spoofing, and man-in-the middle attacks. ADmitMac works with domains configured using Microsoft's Highly Secure (HISEC) security templates, automatically configuring the Macintosh to use Kerberos, obtains the necessary security keys from the domain and performs mutual authentication requiring the server to prove its identify. ADmitMac also works with older NT directory services.

ADmitMac can cache successful user login information for later use. This allows mobile users to use their domain account when not connected to the network.
