systemforcrossdomainidentitymanagementclientnonservicefailure error in EntraID to Oracle IDCS provisioning for some users

Hello Choksi, Neal Manish,

Welcome to the Microsoft Q&A and thank you for posting your questions here.

I understand that you are having systemforcrossdomainidentitymanagementclientnonservicefailure error in EntraID to Oracle IDCS provisioning for some users.

The following steps will help you to resolve it:

Step 1: Use Microsoft Entra provisioning logs to identify:

• Which attribute update is failing.
• Whether the operation is a PATCH, PUT, or POST.

See guides in the following links:

• https://learn.microsoft.com/en-us/entra/identity/monitoring-health/howto-analyze-provisioning-logs
• https://learn.microsoft.com/en-us/entra/identity/monitoring-health/concept-provisioning-logs

Step 2: If you're using customappsso, migrate to scim:

DELETE https://graph.microsoft.com/beta/servicePrincipals/{object-id}/synchronization/jobs/{job-id}
POST https://graph.microsoft.com/beta/servicePrincipals/{object-id}/synchronization/jobs
{
  "templateId": "scim"
}

https://learn.microsoft.com/en-us/entra/identity/app-provisioning/application-provisioning-config-problem-scim-compatibility

Step 3: Append the following to your SCIM endpoint URL: aadOptscim062020

This ensures:

• Boolean values are correctly formatted.
• PATCH operations are SCIM-compliant.

Step 4: Use Oracle’s SCIM error guide to:

• Identify which attributes are immutable.
• Understand how Oracle handles updates to existing users.

Step 5: Reconcile or Re-Provision Existing Users

Options:

• Manual reconciliation to match Entra ID attributes with Oracle IDCS.
• Delete and re-provision to remove the user from Oracle IDCS and allow Entra ID to re-create them.

See Oracle SCIM user sync guide here - https://docs.oracle.com/en/cloud/saas/enterprise-performance-management-common/cgsad/synchronize_with_scim.html
