Hi all, I have this setup : - samba 3.4.8 32bits running on a Mandriva Linux 2010.0 - accounts and groups are in LDAP I needed to have the "administrateur" user to be domain administrator. So I added the options : admin users = administrateur in smb.conf inside the [global] section. My users are able to login on domain members WindowsXP machines. But they are all recognised by Samba as root users : created files or directories have owner root and users have access to every files on shares, because they are all root. I changed the configuration parameter to a group instead of a user: admin users = @administrateurs Restarted Samba. My users are now all normal users, and the members of "administrateurs" group have all root access to shares. So it works correctly with a group. Samba's documentation says that the "admin users" parameter can be set to either users and groups. Dag
