The problem is that corporate users are not being deleted when a delete user is executed from provisioning server. The etanotify logs do show the necessary requests as shown in the below example:
Sending Notification: eTNotifyOpID=a0e07f52-9ef9-4c49-8632-b519a3e6cc09
Event: Delete_Global_User (eTGlobalUserName=testuser)
SeqNo: 0000000002
"View Submitted Task" search is not showing the Delete User Task.
Expected: Corporate user account should also be deleted.
Actual: Corporate user account is not deleted and task does not show up in "View Submitted Task".
This is due to a safety precaution in the product that ensures that you would want to also remove corporate user accounts when deleting global users.
