Looking at your post I am even not sure if you are talking about OX on UCS. I dont think that the MySQL DB was ever accessible with the root password by default. On UCS the file /etc/mysql.secret contains the password.
If you have still problems feel free to start a new thread in the "UCS" or "Mail" section.
