VMware Learning Platform enforces limits on cloud login failures and notifications of failure.
When a cloud login attempt fails, VMware Learning Platform does not attempt another login for one minute. Such cloud login failures can occur in many cases, for example when a tenant admin performs administrative tasks or when an end user tries to take a lab.
Most cloud login failures trigger a notification to the tenant. VMware Learning Platform throttles such notifications such that it only sends one notification within any ten-minute period. Multiple login failures within this ten-minute period do not trigger multiple notifications.
VMware Learning Platform enforces both these limits on a per-node instance and typically runs multiple nodes. As a result, it is possible that it will send more than one notification in a ten-minute period if, for example, different nodes experience a failure during that time.
