That's how I understand it.  On the sites I visited while gathering this 
information, no one seemed to know why it is required, only that 
everything started working after it was added.

I have that line, too and also a lot of other lines regarding BUILTIN.  
Everything is working, so I haven't put any effort into finding out 
why.  If you run "cat" against your Samba logs and grep for BUILTIN, 
you'll see what I mean.

On rare occasions, I've had to do the same thing.  It's something I 
would try when all else failed.

Sorry that I don't have any concrete reasons as to the "why" of any of 
these things.
