How do I join a Windows 2000/2003 Active Directory domain from Linux?

This is specific to Samba 3, earlier versions may operate differently.

After configuring your /etc/samba/smb.conf and your /etc/krb5.conf files, enter the following command:

net ads join –UAdministrator

You will then be prompted to enter the domain administrator’s password. The domain name used will be what you set the workgroup = field to in your smb.conf. To verify that you have joined successfully, look for the server in your directory controller’s server manager.
