AFAIK, there's no logging like that built in. Mainly because it eats up a lot of disk space on large user installs..
However, you might be able to find this information from the access logs (e.g. the log of HTTP requests coming in). This may or may not be turned on. (
Tomcat has this off by default).
You should be able to see the times and IP's the login post screen is called with this. I think there is an option to see the values for "post" forms as well.
Alternatively, you could add in a log4j "debug" or "info" statement info to the UserAction.validateLogin() method and then parse it out of the log files.
