If you enable this in the Auditing section of a group policy
object that impacts the domain controllers, then for each
login using a domain account there will be a record in the
event log of the domain controller that handled the login.
You still need to look at multiple event logs as you likely
have multiple domain controllers. Also, success auditing
of login events can generate a lot of log events if the domain
is of any size / activity, so this may not be the solution that
you want since you would need to read the logs in a script
or with a log read tool like LogParser due to the size.
