OK, I can understand that, but are you saying that if there is a line 
like 'include = /path/to/smb.conf.%M' in smb.conf and there is a file 
called smb.conf.clientname in /path/to , then the contents of that will 
be used instead of what is in the main smb.conf ?

Wouldn't you have to reload the samba config ?

Still mistified
