My customer has 9,000 users in AD corresponding to 7,000 in a locker of which approximately 4,000 are joined (the discrepancy being due to terminated HR users who don't have or need to be provisioned with AD accounts).

When I run a Baseline Sync on my AD link, to revert any unauthorised changes that have been made to users in AD (i.e., disable any accounts that have been manually enabled when they shouldn't have) it takes upwards of 30 minutes to run, during which time all other system processing is blocked (since link operations are blocking).  This doesn't meet customer expectations that unauthorised AD changes should be reverted within a 15-30 minute timeframe and that the system should always process low-latency operations (like manual suspensions using the Suspended Employees feature) with a delay not exceeding a few minutes.

Some possible ways to solve this problem would be to add a "true-up" operation, or allow parallel sync operations.

There is already a Test Mode concept but this appears to be limited when it comes to providing a pre-execution reporting mechanism for ANY pending change to a target system.

Existing MIM Best Practice has incorporated this capability for many years, and the equivalent is now required in the Broker+ and UNIFYConnect platforms

In order to support the unit testing requirements for transitioning PS solutions on Broker+ to the UNIFYConnect hosted platform, a test harness is required for all PowerShell transformations.

We are unable to search the locker using the "Is-Null" Search term. This issue occurs across all environments that I have checked so far.
This search terms works well in Connectors and Adaptors and would be extremely useful for lockers as well.
Any attempt to use the Is-Null Search term in a locker returns the following error:

A UNIFYConnect customer has requested the ability to implement a safety catch feature to stop updates if they are over a certain threshold. I know that Broker/BrokerPlus has a safety catch feature for entity deletion thresholds, but does anything currently exist for updates? Ideally this would be a check that if the number of changes on a link are over X amount it stops the sync, disables the schedules for that link, and then throws an error in the logs to be picked up via the monitoring/alerting.

The only topic I could find on this at the moment is Safety Catch Feature / UNIFYBroker Forum / UNIFY Solutions. 

I have noticed that if a link has a PowerShell task on an outgoing sync task that modifies and sets attributes in the target, then a change flows through to only that attribute modified in the PowerShell task, then the link doesn't pick it up as pending sync change. Only running a baseline sync on the link would trigger the PowerShelltask to change/modify that attribute. 

Discussion was had with Matt Davis on the possibility of using the Register-Contribution function on a link for the attributes that are being modified through the PowerShell task to then recognise changes for those entities. However it is unsure whether the Register-Contribution function is available for links or not. As an alternative, the PowerShell script can be used on the adapter in a reverse transform, which triggers on outgoing sync changes from a link to a connector. Then the contributing attributes can be sync as direct mappings in the link.

I have noticed that under normal operation, a baseline synchronization task on a link cannot be executed while the link is disabled. In the link UI, the option to run a baseline sync only becomes visible when the link is enabled. However I have found that on the Links page (that lists the links in the solution) selecting a disabled link and running a baseline sync through the Actions button at the top of the page still executes the baseline sync on the disabled link. Not sure if this is expected behaviour or is a bug.

Screenshot #1: Running a baseline sync task on a disabled link through the Actions button:

Screenshot #2: The baseline sync still executed even though the link is disabled:

When a locker has inbound provisioning but not inbound deprovisioning it is sometimes desirable to manually delete an entity which is no longer wanted.  A button to do this would be helpful, because the current workaround is to suspend all outbound processing, delete all locker entities and perform a complete data reload.

After a link join is removed using the UI a locker entity retains attribute values that were previously contributed through the link.  This outcome is highly undesirable, since the locker now has information that should not be there (in my case an AD samaccountname value which is misleading, since the the AD user's adapter entity join was removed in order to allow the adapter entity to rejoin to a different locker record, but now both locker records have the same samaccountname value!)  There is no way to initiate removal of this out-of-date attribute data from the locker other than joining the locker to a different adapter entity (which may not be feasible) or performing a complete data reload from scratch (which is time-consuming and an outage).  Running a baseline sync on the link does not fix the problem.  The attribute values on the entity should be updated appropriately when the join is removed.

I renamed a locker field "HRISEmailAddress" to "EmailAddress" in the UNIFYBroker UI, and this stack dump error appeared:

When I tried to get back to the main locker UI page to select the affected locker and fix my mistake the following error now appears every time:

System.ArgumentException: An item with the same key has already been added.

Could you please review the config and fix it so the locker screen works again?
