[Samba] XP SP3 and posix locking

[Adam Williams]

I'm getting the read-only errors in MS Word 2003, and I'm using Symantec 
Endpoint Protection 11 for anti-virus.  One of my techs in his notes has 
reports of read-only errors going back to January 4, 2008.  Samba 3.0.28 
was released on Dec 10, 2007, and I would of upgraded to it soon after, 
so I think a code change in the release of samba 3.0.28 broke 
something.  we've noticed it happens when you open a file, and click 
save, it saves fine, and when youc lick on save again, that is when it 
goes read only.  http://www.lancs.ac.uk/iss/windows/word-readonly.htm 
says that it is because windows desktop search 3.01 will index the file 
after saving it and that makes the computer set it as read only.  i 
uninstalled windows desktop search 3.01 but that didn't help.
