sys - Domain Admins

[Gildas Boichot]

Hi,

Sure this question have already be posted...

How can I make a correspondence between the "sys" group of Linux and the
"Domain Admins" group of Samba ?

I 'have a file domainuser.map where I have placed root="adminstrateur"
and another file domaingroup.map where i have placed sys = "Domain Admins"

for the first file,  in my smb.conf  I use : 

username map = domainuser.map

But I don't know what to use for the second file.
Is anybody has a solution ?
