Hi,

The files and folders on the shared drive are owned by local Linux 
account.  The permissions are read, write and execute by the owner, read 
and write by group and all.  I was hoping that smb.conf will control the 
shared drive access but having a hard time doing so.  I would like to 
use ACL if that is the best way to make it work.   Would you mind giving 
me few pointers or point me to the right direction to get started on 
ACL?  I am no LDAP expert but I think I can get by if I have to use it.

Thanks!
