Is the "Mysql://" part of the connection string capitalized like that? It may be case sensitive (I'm not sure).
It's not capitalized -- my MUA changed it.
Can you log in on the console to that specific MySQL user? Try:
Yes, I can do a linux login as mysql and the password. I did not create this account, this was created by fedora or the mysql install script.
mysql -u drupaluser -h fullhostname -p drupaldatabasename
This does NOT work. However, if I replace fullhostname with localhost, it does.
Does that give you any clues?
