Thanks for your reply. Yes, 'force unknow acl user' option helps to bypass 
the unknown acl info when we need to copy acl with files. But it just 
simply dropped the unknown acl user/group. So is there any workround 
available? Something like add unknow sid to samba db by using pdbedit or 
switch backend to openldap?
