Unix, Linux and Mac have traditionally been managed as standalone systems – each a silo with its own set of users, groups, access control policies, configuration files and passwords to remember. Managing an environment that includes these silos – plus the Microsoft environment – can lead to inconsistent administration for IT, unnecessary complexity for end users and risk to the business. To overcome these challenges, and to achieve consistent policy configuration compliance, a simpler experience for users and administrators, and less risk from an improperly managed system, organizations typically deploy an Active Directory bridge.
