[Samba] Unable to turn off file locking

[Christopher Sohns]

I'm running Samba 3.0.20b with XP and DOS clients.  I have zero issues with 
WindowsXP clients but if I have a XP client accessing a file then try to get
a 
DOS client to access (ro and rw) the same file I'm met with a sharing 
violation.  I've tried all sorts of combinations of the following 
parameters: strict locking, oplocks, level2 oplocks, defer sharing 
violations, locking, and share mode.  No matter what I do, I can not get 
Samba to simple ignore "file locking".  Suggestions?
