This allows synchronization of a user s password from Windows to UNIX as well as from UNIX to Windows. These systems are managed separately and are governed by different access policies.
Many users have to access both systems for a variety of reasons.
Consequently, users need to maintain different user accounts and different passwords on these systems. Maintaining two passwords on two different systems is a hassle for users. It maintains an artificial barrier between two kinds of systems that are part of the same network. With different password update schedules, users may forget one or more of passwords. This will subsequently require administrative intervention to reset them.
