Well, maybe I should have stated or clarified that I made small modifications to the code to remedy the bugs per suggested patches I found.  Oops??  :D

I’ll do my best to get this to you.  I’m sure the dump would be the most helpful, so I’m going to see what I can do.  For the time being, I’m going to investigate and test what Kevin Davidson suggested previously and if that fails or isn’t as good as I would like, maybe we will have some headway for a working Samba install on Mac OS X in the future.

Thanks!
