I have setup Entra ID API driven provisioning (Entra ID cloud) in a clients tenancy. API client is using the std PowerShell offering from Microsoft consuming a CSV. CSV content and PSD mapping files using basic schema at the moment (Core + Enterprise users - no custom). Running PowerShell script as a global admin user.
When I initially set this up and ran with new test users these created correctly and any attribute changes were actioned and reflected in Entra ID.
A few days ago when I went back to testing the same environment by adding extra new users and some existing users (to test initial syncing) it stopped processing the requests. Where as before there were entries in the audit and provisioning logs for the request and subsequent actions they no longer appeared.
I setup another Ent App and updated the service principal in PS script but same issue. Tried generating JSON payload from PS script and using MSGraph (with correct permissions) POSTed a request and got the correct 202 response. Checking Audit, provisioning logs via UI and MsGraph not indication of request. Also tested using PS script hosted on Azure VM (ensuring Azure VM Managed Identity has appropriate permissions) and still same issue.
Attribute mapping in Ent App has been setup for EmployeeID and Username attribute matching.
Using MsGraph to check Sync jobs schedule as active, no quarantine, no errors and always no counts in last execution data.
Kind of out of ideas now
