Quick run down of my setup: NT 4.0 PDC, Samba RedHat 8.0 with samba 2.2.5-10 on it.(Also used RedHat 7.2 with 2.2.6 final as well) with the exact same results. When I run wbinfo -t, I get Secret is bad 0xc000018b. I have been trying to figure this out for a few days now and can't get it working correctly. If I run wbinfo -u, all of the users appears in the list, as well when I run wbinfo -g, I get all of the groups. When I run getent passwd and getent group, everything works their also. Here is my smb.conf: # Samba config file created using SWAT # from xxx01 (127.0.0.1) # Date: 2002/10/16 13:51:21 # Global parameters [global] workgroup = xxx netbios name = xxxx server string = Samba Server %v security = DOMAIN encrypt passwords = Yes min passwd length = 3 map to guest = Bad User obey pam restrictions = Yes password server = * username map = /etc/samba/smbusers log file = /var/%m.log max log size = 0 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 domain logons = Yes os level = 0 preferred master = No local master = No domain master = No dns proxy = No winbind uid = 10000-20000 winbind gid = 10000-20000 template homedir = /homedirs/%D/%U winbind separator = + printer admin = @ntadmin create mask = 0777 printing = cups printer driver location = /usr/local/samba/printers [share] path = /share read only = No guest ok = Yes [secure] comment = test secure path = /share/secure guest account = valid users = xxx+xxxx read only = No Copy of PDC log: [2002/10/18 13:37:54, 0] rpc_client/cli_netlogon.c:cli_net_auth2(157) cli_net_auth2: Error NT_STATUS_NO_TRUST_SAM_ACCOUNT [2002/10/18 13:37:54, 0] rpc_client/cli_login.c:cli_nt_setup_creds(74) cli_nt_setup_creds: auth2 challenge failed [2002/10/18 13:37:54, 0] smbd/password.c:connect_to_domain_password_server(1360) connect_to_domain_password_server: unable to setup the PDC credentials to machine xxxxxxPDC.

I can browse the Samba server and see the shares. The secure share is a no go, get prompted for password, with nothing working. The open share can be seen by everyone. When I added the samba server to the domain using this command: smbpasswd -j xxx -r xxxPDC -U xxx, it came back successfully. The workstation is a NT 4.0 box and we also are testing with a win98 box as well. Any thought would be appreciated. Jason
