[MonetDB-users] can't log in to my own databases...

Hello all, I've installed monetdb from the Feb 2010 source release on a Gentoo 10.1 box. I've created a database (finance), and have released it from administration mode, but every time I try to access it with mclient, I get a prompt for a user name and password, followed by an InvalidCredentialsException:checkCredentials error. When I created the database it didn't ask for any user name or password. How do I get in to my own database?
