[Samba] Archive bit oddities

Hello everyone,

I've been scouring the web, reading documentation and experimenting with 
settings and I am having no luck in getting the behavior of the archive 
bit to be anywhere near expected. I have the file foo.txt in the 
personal folder that has the ADS group DOMAIN USERS with read/write 
capability (660). When the user jsmith (domain user) modifies the file, 
the archive bit is not set. Similarly, CA Brightstor seems incapable of 
clearing the archive bit when doing backups if the backup user is not 
the owner.

It seems to come down to this--if the user isn't the owner, the archive 
bit cannot be automagically cleared by applications. The user can 
manually set and clear, but that doesn't help. Also, unless I 
misunderstand what force user does, that isn't an option for security 

All the stuff I've seen on the lists say that dos filemode = yes and/or 
map archive = yes are what is needed. I've tried all the combinations of 
having those two set/not set and I can say with confidence that in this 
configuration, they patently do not fix the issue.

Any ideas?  Thanks in advance. Configuration below.
