Active Directory Bridge Products: Getting More Value from the Windows Infrastructure

Published: 07 January 2009

ID: G00203638

Analyst(s): Mark Diodati


Senior Analyst Mark Diodati surveys products in the Active Directory (AD) bridge market. Organizations deploy these products (from Centrify, Likewise Software, Quest Software [previously Vintela], and Symark Software) to improve compliance, reduce costs, and reduce user sign-ons. AD bridge products enable the security policy management of UNIX and Mac OS computers, identity management of non-Windows users, and Windows Kerberos single sign-on (SSO) across heterogeneous platforms. Diodati also examines the complexity associated with normalizing the UNIX namespace and makes recommendations for successful deployment and vendor selection.
