I am trying to get Linux-Mandrake (the latest version) to authenticate on a Windows TCP/IP network using DOMAIN security to a NT 4 Server named FEMC1 which is the primary domain controller for the domain FEMC. Linux is installed and functional on the network and Samba is working when the share is public, but I wanted to limit access to only those users who have a valid account in the NT domain. I turned off public access to the share and set SECURITY = DOMAIN and PASSWORD SERVER = * but in order for that to work I understood I had to generate a Microsoft-format machine password for the Linux-Mandrake server.

Logged in as root on bradbury (the linux box), I issued the command,
smbpasswd -j FEMC -r FEMC1

I received this message:
cli_net_auth2: Error NT_STATUS_NO_TRUST_SAM_ACCOUNT
cli_nt_setup_creds: auth2 challenge failed
modify_trust_password: unable to setup the PDC credentials to machine FEMC1.
Error was : NT_STATUS_NO_TRUST_SAM_ACCOUNT.
2002/04/23 12:58:07 : change_trust_account_password: Failed to change password for domain FEMC.
Unable to join domain FEMC.

On FEMC1, in the server manager utility, I can see Bradbury in the list.

Does anyone know what my problem is here?
