Hallo... I use Suse Linux 8.0 with Samba 2.2.7a in a Network with WinNT 4.0 PDC and W2000 Clients. Samba is set as Domain Member with security = Domain. I join Samba to the Domain successfully. So existing users can be validate by WinNT Server. Make Linux user as NT user and fill in File "smbusers" admin = Admin,hans = Hans. Test Samba via smbclient on Server. ...but if I click on the "Linux-Samba-Server" Icon in the "Network environment" on a W2000 Client a dialog opens: "Wrong Password or unknown user for \\LinServer" and fields to enter Name and Password ...if I enter correct Name and Password for NT User the dialog opens again and again. smb.conf (some) ---------------------- workgroup = NT_DOMAIN security = Domain encrypt passwords = Yes password server = NT_S os level = 2 preferred master = No domain master = No ---------------------- Error in "log.smbd" are: ------------------------ rpc_client/cli_netlogon.c:cli_net_sam_logon_internal(406) cli_net_sam_logon_internal: NT_STATUS_NO_SUCH_USER smbd/password.c:domain_client_validate(1619) domain_client_validate: unable to validate password for user xxx in domain APC to Domain controller NT_S. Error was NT_STATUS_NO_SUCH_USER smbd/password.c:pass_check_smb(545) Coudn't find user 'xxx' in passdb. smbd/reply_sesssetup_and_X(1001) Rejecting user 'xxx': authentication failed ----------------------------------------------- ...user xxx in domain APC could be wrong? Domain Name is "NT_DOMAIN" and "APC" is the PC name of the Client where i try to access to LinServer. If I change security option in smb.conf from "Domain" to "server" everything is ok. I see 2 share Directories. Home Directory of the user and a "forall" Directory. No Dialog opens for enter Name or Password. But it takes 5-10 Seconds to access and open the Directories. Can I make the access over "server" option faster?? Or what is wrong with the "domain" option and Error NT_STATUS_NO_SUCH_USER?
