The PswdSync subkey stores configuration data for the Password Synchronization Service. The Password Synchronization Service lets users use a single password for computers that are running Windows Server 2003 and UNIX. It ensures that any password changes made in Windows Server 2003 are communicated to the UNIX system, in encrypted text. It also ensures that all passwords conform to the security standards implemented on the system by notification packages, such as Passfilt.dll.

The PswdSync subkey contains two subkeys, Domains Subkey and NotifyChange. The Domains subkey contains UNIX-system-name subkeys, each of which represents a UNIX system and stores data that applies to only to that system. The NotifyChange subkey is used internally by the Password Synchronization Service to detect and implement configuration changes while the service is running. Do not delete or change it.

The PswdSync subkey can also contain entries. The entries in PswdSync apply to all UNIX systems. These entries can also appear in the PswdSync\Domains\UNIX-system-name subkeys, where they apply only to the UNIX systems. If the same entry appears in the PswdSync subkey and in a UNIX-system-name subkey, then the value in the UNIX-system-name subkey takes precedence over the value in PswdSync when configuring that UNIX system.

Change Method

To change the value of the entries in this subkey, use the Password Synchronization wizard in Services for UNIX Administrator. Do not edit the registry.


  • The Pswdsync subkey appears in the registry when you configure the Password Synchronization Service by using the Password Synchronization wizard in Services for UNIX Administrator.
