We recently had the case that our Entra deleted users by accident and this triggered the deactivation of users in meshStack.
Entra team created new users, the new users got new object ids.
After 30 days, Entra sent a delete command to meshStack for the users with the old object ids. This triggered a deletion of users in meshStack.
Expected: meshStack SCIM sync differentiates users by object id, not by username.
