Ah, yes, I have some recollection of that.  I forget how, exactly, but I
thought that I found a way around that.

I agree 110%.  It really needs to use the existing credentials, though
it's nice that this shows the basic capability working.

I'll try to find some time to test my setup again and see if I can find
a way to do that.  Of course, part of the problem here will end up being
silly applications that insist on being given a username and password.
It'd be nice if those could be left blank, but even so, users will end
up being annoyed by it. :(  My primary JDBC app at the moment is uDig,
in case anyone's listening. ;)

Please update us on how that goes. :)
