User synchronization

Synchronization using network users solves the problem of how to change user properties in a large system with multiple, separate stations, each of which has the same set of users. Network users under the NiagaraNetwork facilitate centralized user management.

User synchronization requires these prerequisites and is limited by these factors.

  • Both Supervisor and controller stations must use compatible password storage mechanisms. Otherwise, user synchronization fails and the corresponding NiagaraStation’s users device extension reports fault.

  • Niagara 4 supports synchronize–in and synchronize-out between N4 stations (N4-to-N4). However, when synchronizing between N4 and AX stations, you can only synchronize-out from an N4 station to an AX station (N4-to-AX).

  • Roles are not created during the synchronization process. For any role assigned to a network user in the sending station, you must set up a matching role on the receiving station.

  • If a NiagaraStation reports a one-way password hashing support mismatch, the remote controller station is running a version of Niagara that is earlier than AX-3.7U1. Migrate the remote controller station to N4 before you configure and attempt user synchronization.
