One point that isn't highlighted enough in the install docs for Openfire. The first time that you attempt to login as the "admin" user, DON'T ENTER ANYTHING IN THE PASSWORD FIELD! If you do, the login attempt will likely fail and you'll need to manually reset the password. For those that use the external database, reseting the Openfire admin password is easy (scroll down to step 22). For those that use the embedded database, it looks like the easiest way out is to re-install.
