Bug #: 50000300 (SQL Hotfix)


Notice

Microsoft distributes Microsoft SQL Server 2005 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release.

This article describes the following about this hotfix release:

  • The issues that are fixed by this hotfix package
  • The prerequisites for installing the hotfix package
  • Information about whether you must restart the computer after you install the hotfix package
  • Information about whether the hotfix package is replaced by any other hotfix package
  • Information about whether you must make any registry changes
  • The files that are contained in the hotfix package


SYMPTOMS

In SQL Server 2005, you receive a "Logon Error: 18456" error message when you try to log on to an instance of SQL Server 2005 and the following conditions are true:

  • You try to use a SQL Server authenticated login to log on to the instance.
  • The SQL Server service is configured to use a domain account for the service startup account.
  • The SQL authenticated logins that receive the "Logon Error: 18456" error message are configured to use Windows domain password policy enforcement.


Note By default, Windows domain password policy enforcement for SQL authenticated logins is enabled unless you explicitly set the CHECK_POLICY clause of the CREATE LOGIN statement to OFF when you create a given login.

  • The service account for the SQL Server startup service is locked or disabled on the domain controller.

If login auditing is configured to write the event of failed logins to the error log for the instance of SQL Server, the following messages are written to the SQL Server Errorlog file:

Error message 1


DateTime Logon Error: 18456, Severity: 14, State: 10.

Error message 2


DateTime Logon Login failed for user '<username>'. [CLIENT: <IP Address>]

Note The state of this 18456 error is 10. However, you always receive this "Logon Error: 18456" error message that has a state set to 1 in the client application. To increase security, the error message that is returned to the client deliberately hides the nature of the authentication error by always setting the state of the 18456 error to 1. By default, auditing of failed logins is enabled. In this case, the true state of the 18456 error is reported in the SQL Server Errorlog file. For more information about how to troubleshoot 18456 errors, visit the following Microsoft Developer Network (MSDN) Web site:

WORKAROUND

To work around this problem, use one of the following methods:

  • Unlock the service account on the domain controller.
  • Do not use Windows domain password policy enforcement for SQL Server authenticated logins. To disable this property, use the following statements:
    • For a new SQL Server login

      CREATE LOGIN <SQLAuthenticatedLogin> with PASSWORD = <StrongPassword>, CHECK_POLICY = OFF
    • For an existing SQL Server login

      ALTER LOGIN <SQLAuthenticatedLogin> with CHECK_POLICY = OFF


STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

This hotfix adds the new trace flag 4614 to SQL Server 2005. When you enable trace flag 4614, you can use SQL Server authenticated logins that use Windows domain password policy enforcement to log on to the instance even though the SQL Server service account is locked out or disabled on the Windows domain controller.

You can interactively enable or disable the trace flag by using the following DBCC TRACEON and DBCC TRACEOFF commands:

  • Enable trace flag 4614

DBCC TRACEON (4614, -1)

  • Disable trace flag 4614

DBCC TRACEOFF (4614, -1)

You can also specify the trace flag as a startup parameter of the SQL Server service. When you specify the trace flag as a startup parameter, the trace flag is automatically enabled when the SQL Server service starts. If you set the trace flag as a startup parameter, you can still use the DBCC TRACEOFF command to disable the trace flag interactively.
