Hello I joined an NT 4.0 Domain with Samba running on a Redhat 8.0 box.. However I'm trying to get Samba to authenticate Domain users for samba shares using the NT 4.0's PDC. I can't seem to get it to authenticate correctly and I'm not sure what's wrong. To log in, I tried using "Domain\user" or just "user" but none of those seem to be working.. To authenticate under samba using an NT domain's users I would need WinBind correct? I set that up correctly i believe though I dont know of any way of testing that it is correct. Some of the errors I'm getting in the Samba error logs are the following: [2003/02/10 16:02:07, 0] smbd/password.c:connect_to_domain_password_server(1367) connect_to_domain_password_server: unable to setup the PDC credentials to machine HUDSON. Error was : NT_STATUS_OK. [2003/02/10 16:02:07, 0] rpc_client/cli_netlogon.c:cli_net_auth2(157) cli_net_auth2: Error NT_STATUS_NO_TRUST_SAM_ACCOUNT [2003/02/10 16:02:07, 0] rpc_client/cli_login.c:cli_nt_setup_creds(72) cli_nt_setup_creds: auth2 challenge failed Any help would be greatly appreciated.. Thanks Alex
