[Samba] Member of DOM1, but user authentication on DOM2?

[Kraa de Simon]

Using version 2.2.8a.

My server must be a member of MY_RESOURCES, but user authentication must be
done on MY_USERS_DOM.

How can I accomplish this?

smbpasswd -j MY_USERS_DOM?????

[global]
	workgroup = MY_RESOURCES?????
	netbios name = MY_SERVER?????
	security = DOMAIN?????
	password server = PDC_MY_USERS_DOM, BDC_MY_USERS_DOM?????

Thanks,

Simon.
