read/write,write/write lock with smbclient fails

Hi,
We have smb client running on two of the linux boxes and smb server on another linux system. During a backup operation which uses smb, read of a file was allowed while write to the same file was going on.Also simultaneous writes to the same file were allowed.Following are the settings in the smb.conf file:
lock directory =/var/samba/lock
locking=yes
strict locking = no
oplocks=yes
level2 oplocks = no
kernel oplocks =yes
raw read= yes
raw write = yes
Could anyone please let me know that what can I do to disallow read while write is going on and also restrict simultaneous writes?

NAME
locktest - Find differences in locking between two SMB servers SYNOPSIS
locktest {//server1/share1} {//server2/share2} [-U user%pass] [-U user%pass] [-s seed] [-o numops] [-a] [-O] [-E] [-Z] [-R range] [-B base] [-M min] DESCRIPTION
locktest is a utility for detecting differences in behaviour in locking between SMB servers. It will run a random set of locking operations against //server1/share1 and then the same random set against //server2/share2 and display the differences in the responses it gets. This utility is used by the Samba team to find differences in behaviour between Samba and Windows servers. OPTIONS
-U user%pass Specify the user and password to use when logging on on the shares. This parameter can be specified twice (once for the first server, once for the second). -s seed Seed the random number generator with the specified value. -o numops Set the number of operations to perform. -a Print the operations that are performed. -A Backtrack to find minimal number of operations required to make the response to a certain call differ. -O Enable oplocks. -u Hide unlock fails. -E enable exact error code checking -Z enable the zero/zero lock -R range set lock range -B base set lock base -M min set min lock length -k Use kerberos VERSION
This man page is correct for version 4.0 of the Samba suite. SEE ALSO

This utility is part of the Samba[1] suite, which is developed by the global Samba Team[2]. locktest was written by Andrew Tridgell. This manpage was written by Jelmer Vernooij. NOTES
