On my old server I tar'd up the osticket directory on my web server and moved it to my new machine (Apple Lion Server). I manually installed mysql and did a database restore. If I run the following command from a terminal session, I immediately connect to the osticket database. However, any attempt to access this area from the web results in a message saying fatal error, contact system administrator.

mysql -u localhost -u root -p osticket

Those are the entries in ost-config.php for DBHOST, DBNAME, DBUSER. I made sure to type the exact DBPASS value for the password.
