[Samba] force user not working

[Chris]

Hello.

I am making a new samba server.  My old samba server was a RedHat machine 
(6.2) with samba 2.0.7 on it.  My new samba server is a Gentoo machine with 
Samba 3.0.2a.

Aside from the fact that I am now using ADS instead of a traditional NT4 
domain -- everything else is the same.  I am keeping all the shares the same, 
I have synced all the gid's and uid's between the two machines, and I rsynced 
all the files and directories over from the old machine so that all the 
permissions and ownerships are the same between the two machines.

For some reason, on the new machine, my "Force User =" is not working.  All 
files are owned by root no matter what -- not the user that created them.
For all of my common directories (each dept has a commond dir that only their 
dept can access) I have "Force User = %U".  This is important, because 
without it the created files do not apply to the user's quota.  

I wish to stress that this did *not* happen with 2.0.7... it worked just as it 
should.

Could someone please give me a hand here?

TIA

Chris
