You are providing an invalid mysql username password or the mysql user does not have priviliges to connect to the database.

i had this site working with a web hoster now im trying to get it up and running on my home web server, running mac os x server... i got mysql running... and i have a backup database file from my old web hoster... its a .sql file.... im guessing i have to restore it... how exactly would i go on doing that??

If you have created .sql file with mysqldump or exported via phpMyAdmin, simply type the following command on command prompt
Replace MYSQL-USERNAME with a valid mysql username. On hitting enter, it will ask for Mysql username password.

After importing the data, create a valid username which can access your site database. Provide this username and password in your site connection parameters.
Read this page for detail information about exporting and importing .sql files.
