Due to the fact that I can't tell if you have made any changes to your 
mysql server let alone what the password is for it you will have
to configure the mysql server by hand.

There is a file in imp/lib/scripts that all you have to do is
run the command:

mysql < mysql_create.sql

and it will populate your database for you.  That exact command
line will only work if you run it from root and mysql has no
password set for the root account.  Please note that the
database configuration in the mysql_create_users.sql matches that
which is configured within imp.  This way if you install imp and
then setup your mysql database using the example above, it should
work out of the box.  You will need to restart both your mysql
server and apache after this.  If you make changes to the name of
the database, the manager name or password, you will need to make
the same changes to your config/defaults.php3 file as well.
