Hi, we're running Samba 2.0.05beta on a Linux 2.0.36 box. We have problems with authentification. Samba is running in security-mode 'SERVER'. About 20 users access this server. As a PDC we have NT 4.0 SP4. Sometimes the PDC rejected the password: NT Msg: Logon Failure: Reason: Unknown user name or bad password User Name: USERX Domain: MGM Logon Type: 3 Logon Process: KSecDD Authentication Package: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0 Workstation Name: \\MGM-FILE About two times a day, this happens so often, that the NT User Account is locked out: User Account Locked Out: Target Account Name: USERX Target Account ID: S-1-5-21-2115134065-900400532-444732941-1330 Caller Machine Name: \\MGM-FILE Caller User Name: SYSTEM Caller Domain: NT AUTHORITY Caller Logon ID: (0x0,0x3E7) Then samba says: [1999/01/14 10:26:54, 1] smbd/password.c:server_validate(1121) password server MGMS1 rejected the password [1999/01/14 10:26:54, 0] smbd/reply.c:reply_sesssetup_and_X(771) NT Password did not match ! Defaulting to Lanman This is OK, but why is the user locked out? If you have any suggestions, please let me know.
