How can I monitor and track locked out accounts in AD.
UDT does not have that capability. I think you might want to check with Server and Applications Monitor.
You can do this with appinsight for AD in SAM as donrobert5 suggested.
AppInsight for Active Directory
While this is true that it will inform when you have a locked out account, in most large environments that's not particularly interesting. More useful is a way to alert when a specific account is due to expire in X number of days and when that same account, perhaps a service account, is locked.
