Thursby Software is a longtime Mac development firm (since 1986) that has always had a mission: integrating Macs as full players in mixed-OS environments. While Mac OS X has gone a long way toward improving the situation of Mac users in predominantly Microsoft environments, there are still situations where third-party software may be required. Thursby's ADmitMac line of software is specifically designed to ease Mac integration into Microsoft Active Directory (AD) environments.
Thursby's ADmitMac for PIV integrates US Government FIPS 201 Personal Identity Verification (PIV) with Macs. ADPIV, as the product is known, allows single sign-on with a PIV card. It verifies the PIV card against a centralized authority, obtains Kerberos tickets using PIV certificates and then makes those tickets available to Kerberized applications, and securely locks the Mac upon removal of the PIV card.
ADPIV also allows password-free access to Exchange servers by providing authentication to those servers. ADPIV is currently available at the introductory price of US$149, with discounts available for larger quantities.
