One of the biggest challenges facing heterogeneous enterprises is providing secure access, authentication, and authorization of users to all systems, regardless of platform. Microsoft Active Directory (AD) has proven ideal in meeting this objective for Windows resources. Unfortunately, by itself AD can't provide the same level of security, compliance, and scalability to Unix, Linux, and Java systems. Quest Software can bridge that gap by natively integrating the same standards that make AD so powerful for Windows systems on non-Windows systems. The result is a single, proven, and powerful access, authentication, and authorization mechanism for all systems and platforms based on the already ubiquitous AD infrastructure.
