[CipherMail User] Changing MySQL credentials

If I wanted to change MySQL credentials for Ciphermail, what config files would I have to modify? The installation Guide only seems to mention the /usr/share/djigzo/conf/database/hibernate.mysql.connection.xml file, but the /usr/share/djigzo/conf/database/hibernate.mysql.cfg.xml also seems to have the MySQL crendentials in it. Does the /usr/share/djigzo/conf/database/hibernate.mysql.cfg.xml get generated automatically by the system? Thanks a lot
