[Samba] Modify but not create permissions

Yeah, I have a valid users statement.  From what I can tell the uid and gid on 
the mount were being ignored by the server, which had a different uid than my 
local machine.  

For what I am doing, the nfs security (which is not much) is good enough.  I 
have most mounted read only, and some others limited by IP.  I know that can 
be spoofed, but its a private lan with only a few users that if they wanted 
to could trounce the box anyway.

I have just found that bug with homesite breaking on 3.0.4, so maybe my other 
problem is also a bug.  Who knows.

Thanks for the feedback anyway

Without good motivation, science and technology, instead of helping, bring 
more fear and threaten global destruction. Compassionate thought is very 
important for humankind.
-His Holiness the Dalai Lama

Wisdom does not mean knowledge but experiential understanding. Wisdom helps 
you to change radically your habits and perceptions, as you discover the 
constantly changing, interconnected nature of the whole of existence.
