+To connect to mysql, backupninja must authenticate.
+There are three possible authentication methods:
+
+USER
+With this method, you specify a system user. Backupninja will
+then become this user before running mysqldump or mysqlhotcopy.
+The result is that ~/.my.cnf is used for authentication.
+
+PASSWORD
+With this method, you manually specify a mysql user and
+password in the backup action configuration.
+
+DEBIAN
+With this method, we use the debian-sys-maint user which is
+already defined in /etc/mysql/debian.cnf. If you are running
+debian, this is recommended, because no further configuration
+is needed. The drawback is that this is incompatible with
+mysqlhotcopy: you must use mysqldump.
