Lost admin pwd


I installed Lucee 5.2 onto a ubuntu box a while ago and totally forgot its admin pwd.
Started a terminal session, under “tomcat” directory, I noticed we have “conf” and “lucee-server” sub directories, took a look at the “conf” subdirectory, and noticed server.xml, web.xml conf files, however, I don’t see lucee-server.xml file there, the “lucee-server” subdirectory and its subsubdictories do not seem to contain lucee-server.xml conf file. What do I do now?
