Oh, I've traced through my code and I know that it's doing what it should and reading the correct section of the defaults file. The problem is that DBD::mysql does not appear to be passing along the host specification along with the username and password, and I'm wondering whether I have missed something in my usage. The documentation leads me to believe that it SHOULD be working, but it isn't.
