1) a little bit more information would be great: is this a server or a workstation? if its a workstation: do in the gui: choose: -systemtools or settings (no sure, doing it by head) in the menu -select authentication -choose in both registers each samba and winbind. indicate there your domain-name and server-name ..you should be done, your machine should now be in the windows-domain if its a server: -please tell me the security settings in the smb.conf. is it user, server, ads, domain?
