Logging config bundled with installers is too strict

The log4j.properties in installers sets most log levels to FATAL. The consequence is that there is no log output at all. Especially the warning

You didn't change the admin password of directory service instance 'default'.  Please update the admin password as soon as possible to prevent a possible security breach.

is not printed.

I'd suggest to change from FATAL to WARN.
