Is there a way to be notified via email when LFDS has a sync error? If not, can this be requested as a future enhancement?
Please see this earlier response I wrote about Directory Server group sync error notifications: https://answers.laserfiche.com/questions/216305/Why-does-LFDS-synch-fail-for-69K-records-when-only-1-has-an-error-Also-why-no-notifications#216371
Long story short - LFDS logs a Windows Event message with a specific Event ID when a group sync error occurs. There are various ways to watch for this event (e.g., Windows Task Scheduler) and trigger actions like email notifications (or a PowerShell script that sends an email notification) in response.
We have feature requests and user stories filed for a variety of enhancements to LFDS AD group sync logging that would be targeted for Laserfiche 12 (not necessarily the initial release). #528394 is "Add email notifications for AD group sync errors".
