This can occur when you have a soft-deleted RM Unify staff or student account and have set the Network Agent to run a full sync of all users. With a full sync, Network Agent will process messages for all active and soft-deleted RM Unify staff and student accounts.
In the case of soft-deleted RM Unify accounts, the Network Agent will receive a message to disable the linked AD account if it finds it. This is to handle a use case where the AD account has been disabled after its linked RM Unify user account has been deleted, but is subsequently re-enabled directly in AD. The Network Agent is designed to disable the AD account again to reflect that its linked RM Unify user account is in a deleted state. (By design, if an RM Unify account is deleted, the Network Agent will only disable the linked AD account in case the account needs to be temporarily retained. The network administrator is responsible for deleting the AD account).
The OBJECTNOTFOUND error is therefore generated because the Network Agent has been unable to find the linked AD account, usually because the AD account has already been deleted. You can safely ignore this error if it relates to a soft-deleted RM Unify user and the AD account does not exist.
The RM Unify user audit log contains the error but an AD account with the username does exist
This can occur if an RM Unify user has been deleted and a new RM Unify user created with the same username. The appearance of this error message in the RM Unify audit log may look like there is an issue with the active RM Unify user, but actually it is only the Network Agent processing the soft-deleted user. What has happened is that the Network Agent has retrieved both RM Unify accounts with the same username but different GUIDs (active and soft-deleted) and processed both account messages separately. It creates an AD account for the active RM Unify user, and tries to disable an AD account for the soft-deleted user.
For example, an RM Unify student with name 'JSmith' has been deleted and a new one created. The Network Agent is set to complete a full resync and the following messages will appear In the RM Unify user audit log:
JSmith Create AD User SUCCESS: User: JSmith
JSmith Disable AD User OBJECTNOTFOUND: User: JSmith A user with the specified ID could not be found
The Create AD User message relates to the active RM Unify user and for which the Network Agent creates a linked AD account. The Disable AD User message relates to the soft-deleted user and for which the Network Agent has tried but failed to find the linked AD account in order to disable it. The Network Agent is not trying to complete both actions on the same AD account. |
