Adjust your MySQL authentification information

[Sneeper]

In the instructions (IV.3. Open-Xchange Database) there is this little line that says;

"Adjust your MySQL authentification information (OXDB_USER_*) in /opt/open-xchange/sbin/oxinstaller"

What exactly does this mean?

In the file there are a number of, not sure how to describe it, but perhaps empty field values?

# some defaults
OXDB_USER=openexchange
OXDB_USER_LONG=oxdb-user
OXDB_PASS=
OXDB_PASS_LONG=oxdb-pass
OXDB_HOST=localhost
OXDB_HOST_LONG=oxdb-host
OXDB_PORT=3306
OXDB_PORT_LONG=oxdb-port
OXADMIN_PASS=
OXADMIN_PASS_LONG=admin-pass
MAIL_DOMAIN=
MAIL_DOMAIN_LONG=maildomain
MAIL_HOSTNAME=
MAIL_HOSTNAME_LONG=mailhostname
INST_LANGUAGE=en_US
INST_LANGUAGE_LONG=language
INST_LANGUAGE_VALUES="de_DE en_US"

FORCE_DB=
SYSINST=
SCANMAIL=
LOG2SYSLOG=

Am I supposed to fill in the values after the equal signs that are blank? If so, what would the values look like?
