Password synchronization automatically updates passwords so they are the same for associated accounts in all configured security domains. The user, or a privileged administrator, can initiate a password change on any host or Windows NT computer, and the password synchronization feature will apply the change to the rest of the security domains.
Password synchronization must be configured by the system administrator before use. Synchronization changes can be sent in both directions or limited to only one direction. In addition, a user can selectively enable synchronization for only some of his or her host computer accounts.
Generally, specific third-party software must usually be installed on host computers for password synchronization to work. The exception is AS/400s running V3R1 or later, for which SNA Server provides built-in support for unidirectional synchronization, applying Windows NT changes to the AS/400. It can be enabled on Windows NT or the AS/400 without any additional host code.
For password synchronization to work in a Windows NT security domain, the user must be running on a 32-bit platform and must be logged into the Windows NT domain. Alternatively, the Windows NT security administrator can initiate a password change for the user.
