Hi, All.  We are using samba on an SL5.2 server to share filesystems  
with our Windows systems.  Everything works properly when sharing a  
filesystem that is local to the samba server.  When sharing an nfs  
filesystem, however, we see locking issues with *some* file types.

For example, we can only open doc or ppt files read-only using MS  
Office on Windows, and get erroneous errors saying that the file is  
locked or already being modified.  If you save the file to your  
desktop and than drag it back to the samba share, it copies over  
without problem.  We can also open txt files using word and edit and  
save them directly onto the share without incident.  We only see this  
problem on Windows clients, as a Mac can edit doc and ppt files  
directly on the share.

I am not able to reproduce this on an SL4 samba server using the exact  
same smb.conf.  In addition, the problem remains after updating samba  
on SL5 to 3.0.33-3.7 from 5rolling.

So far the only "solutions" we've found, neither of which I'm  
comfortable with, are to disable locking ("locking = no") or enable  
fake oplocks ("fake oplocks = yes").

Has anyone else encountered this?  Any suggestions would be greatly  
appreciated.

Thanks,
Devin
