Symptoms

Consider the following scenarios:

Scenario1
  • You install the Active Directory Lightweight Directory Services (AD LDS) role on a computer that is running Windows Server 2008 R2.
  • You enable an account lockout policy on an AD LDS instance.
  • The policy is triggered when the BadPasswordCount value exceeds the specified threshold. Therefore, the AD LDS user is locked out.
  • You enter a password to perform an LDAP bind to the locked-out account.
In this scenario, one of the following situations occurs:
  • If you enter a correct password, you receive an "Account locked out" error.
  • If you enter an incorrect password, you receive an "Unknown username or bad password" error.
Scenario 2
  • You install the Active Directory Lightweight Directory Services (AD LDS) role on a computer that is running Windows Server 2008 R2.
  • You enable an account lockout policy on an AD LDS instance.
  • You enter a password to perform an LDAP bind to a user account that has an expired password.
In this scenario, one of the following situations occurs:
  • If you enter an incorrect password, you receive an "Unknown username or bad password" error.
  • If you enter a correct password, you receive an ERROR_PASSWORD_EXPIRED error. If the User must change password at next logon option is enabled, an ERROR_PASSWORD_MUST_CHANGE error is received instead.

Additionally, the BadPasswordCount property does not increase in “Scenario 2”. Therefore, there is no retry limit.

(http://technet.microsoft.com/en-us/security/advisory/2749655)
.

A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing the problem described in this article. This hotfix might receive additional testing.

File information

The global version of this hotfix installs files that have the attributes that are listed in the following tables. The dates and the times for these files are listed in Coordinated Universal Time (UTC). The dates and the times for these files on your local computer are displayed in your local time together with your current daylight saving time (DST) bias. Additionally, the dates and the times may change when you perform certain operations on the files.
Windows Server 2008 R2 file information notes
Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:
    Collapse this tableExpand this table
    VersionProductMilestoneService branch
    6.1.760 0.17xxxWindows Server 2008 R2RTMGDR
    6.1.760 0.21xxxWindows Server 2008 R2RTMLDR
    6.1.760 1.17xxxWindows Server 2008 R2SP1GDR
    6.1.760 1.22xxxWindows Server 2008 R2SP1LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • The MANIFEST files (.manifest) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2" section. MANIFEST files and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
