By design Windows workstations treat users belonging to the Domain 
Admins group as Adminstrators (the Domain Admins group become member of 
the local Administrators group when the workstation joins the domain).
As Samba needs a posix account for each samba account (even for 
workstations), and on *nix only root (uid=0) can create users 
(accounts), you need a way to tell samba to threat some users as root. 
This is the reason of existance for the admin users smb.conf parameter. 
Specify admin users = @domainjoiners in the global section, and members 
of the domainjoiners group will be able to create accounts, and do all 
the nasty things allowed only to root (add/remove/modify shares/users) 
(if you configure them in smb.conf). You can limit their access to 
files/folders, by specifying admin users = root on the share definitions.

Good Luck!
