Hmm.. I think you might be right, actually...

The two passwords above are default on install, so the salt (and hash) is
probably the same for all installations, just checked another db and the
regular users passwords DO appear to be salted.... My mistake...

Ok, so ammendments to first post statements:

Passwords are NOT case sensitive and there is probably one byte salt.
Passwords are not limited to 7 or 8 chars, either....

Anyone have a clue as to what it might be?
