[Samba] File / Record Locking In Samba

[James.Campbell at idelta.co.uk]

I would like to use  Linux as a  file and print server for a number of 
Windows workstations. 

One use of this is server will be to provide a central repository for an 
accounting package. 

I have spoken to the software supplier for the accounting software  and 
whilst they do not know of any issues with this configuration,  they have 
advised they are unsure how Samba manages file/record locking, and the 
potential impact on their application

To obtain the software supplier's support of this configuration I would 
like to go back to them with some detail on which CIFS/SMB standard  Samba 
 adheres to for these functions. 

Can anyone advise if  such a standard exists for  windows file and record 
locking, if so which version does Samba Ver 3. adhere to

Cheers

James
