[Samba] How can we let all the clients determine we have changed the share's permission

[chenyun_zhou]

 As we know, if we change the permission of windows' file share's permission, the client will determine this. But if we change the file share's permission in the smb.conf , the client can not determine this if it aready connected to the server. How can we let all the samba clients determine the smb.conf's change immediately?
 
Thanks a lot!
