Installed the openfire.deb on Ubuntu, where is the openfire.xml?

I’ve installed, uninstalled, reninstalled the newest openfire.deb multiple times and searched everywhere for the openfire.xml file. I’ve read that its in the conf directory but it doesn’t seem to be for me. I need to reinstall openfire because it takes me to the admin login page and I have no idea what my login is. Any help would be much appreciated.
