Vulnerability details for the current month:

Below are summaries for some of the security vulnerabilities in this release. These specific vulnerabilities were selected from the larger set of vulnerabilities in the release for one or more of the following reasons: 1) We received inquiries regarding the vulnerability; 2) the vulnerability may have received attention in the trade press; or 3) the vulnerability is potentially more impactful than others in the release. Because we do not provide summaries for every vulnerability in the release, you should review the content in the Security Update Guide for information not provided in these summaries.

Notes on details in the vulnerability summaries:

Attack VectorThis metric reflects the context by which vulnerability exploitation is possible. The Base Score increases the more remote (logically, and physically) an attacker can be in order to exploit the vulnerable component.
Attack ComplexityThis metric describes the conditions beyond the attacker’s control that must exist in order to exploit the vulnerability. Such conditions may require the collection of more information about the target or computational exceptions. The assessment of this metric excludes any requirements for user interaction in order to exploit the vulnerability. If a specific configuration is required for an attack to succeed, the Base metrics should be scored assuming the vulnerable component is in that configuration.
Privileges RequiredThis metric describes the level of privileges an attacker must possess before successfully exploiting the vulnerability.
User InteractionThis metric captures the requirement for a user, other than the attacker, to participate in the successful compromise the vulnerable component. This metric determines whether the vulnerability can be exploited solely at the will of the attacker, or whether a separate user (or user-initiated process) must participate in some manner.

ConfigMgr Reporting Error – UserTokenSIDs LDAP Server Unavailable

I recently switched to using my new-ish laptop (Lenovo P1) for my day-to-day technical work and decided I should redo my test lab in Hyper-V, particularly for my ConfigMgr / MEMCM / Intune testing and troubleshooting stuff. While I have been actively using my ConfigMgr site in my lab, I didn’t pay much attention to the built-in reports until very recently, when I discovered I had an issue as all the reports produced an error.

The Component Status in the Monitoring node of the ConfigMgr console indicated no issues with the Reporting Services Point Role.

The Site Status was lit up nice and green and indicated all was working fine with my ConfigMgr site.

When a report is run from the ConfigMgr console or SSRS, the following error is produced (see image above):

The DefaultValue expression for the report parameter ‘UserTokenSIDs’ contains an error: The LDAP server is unavailable. (rsRuntimeErrorInExpression)

The full error is provided below:

System.Web.Services.Protocols.SoapException: The DefaultValue expression for the report parameter ‘UserTokenSIDs’ contains an error: The LDAP server is unavailable.

at System.ComponentModel.BackgroundWorker.OnDoWork(DoWorkEventArgs e)
at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument)


I tried several troubleshooting steps including the following:

1. Uninstalled the Reporting role from ConfigMgr
2. Uninstalled the SQL Reporting Services
3. Reinstalled SQL Reporting Services
4. Reinstalled the Reporting role in ConfigMgr
5. Changed the registry key: “HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node/Microsoft/ConfigMgr10/
AdminUI/Reporting/ReportBuilderApplicationManifestName” from the value “ReportBuilder_2_0_0_0.application” to “ReportBuilder_3_0_0_0.application”
6. Edited the file:
“C:\Program Files (x86)\Microsoft Configuration
Manager\AdminConsole\bin\Microsoft.ConfigurationManagement.exe.config” and changed the 2 to a 3 in the two locations:
<add key=”10.0″ value=”ReportBuilder_3_0_0_0.application”/>
<add key=”DEFAULT” value=”ReportBuilder_3_0_0_0.application”/>
7. Checked accounts including the service account for SQL reporting

None of the above steps helped fix the UserTokenSIDs issue. I searched high and low on Google / Bing and did not discover anything regarding “LDAP server is unavailable” specifically relating to UserTokenSIDs. I finally got the big guns out and contacted my close friend, Garth Jones, who is a known industry expert with SQL and SSRS. He is a Microsoft MVP and also owns a company called Enhansoft which provides a subscription service for all things reports, which extends the reporting capabilities in ConfigMgr. Enhansoft also provides a free report as a giveaway each month.

RESOLUTION:

With Garth’s help, the issue was quickly discovered and fixed quite easily. Bottom line is that I was using a local administrator account (CM01\Administrator) to login to my ConfigMgr server as opposed to using a Domain account (Dhalico\Harjit) with the necessary privileges. FYI, “Dhalico” is my domain.
1. Added the Dhalico\Harjit account in the ConfigMgr console under
Administration > Overview > Security > Administrative Users (see image below)
2. Provided “Full Administrator” security role
3. Logged on to the ConfigMgr server as “Harjit” and tested running reports
4. Success! And Thank you Garth! 🙂

How To Install ConfigMgr Client On VDI Template

The installation of the ConfigMgr client on workstations and servers is pretty straight forward, and can be done manually, with Client Push, and Software Update Based client installation to name a few. However, it is not as simple when dealing with Windows VDI systems, where extra steps need to be taken to avoid duplicate ConfigMgr client GUIDs and certificates on cloned VDI systems. Below are the steps to follow.

On the master or template system:

  1. Install the ConfigMgr client. Ensure it is properly functioning and has all the necessary components and actions.
  2. Stop the SMS Host Service. This can be done by launching the Command Prompt (CMD) as Administrator and running the following command:
    net stop ccmexec
  3. Delete the SMSCFG.ini file from the Windows folder location. In Administrator CMD, run the following command:
    del %WINDIR%\SMSCFG.ini
  4. Delete the SMS Certificates. To do this, launch PowerShell as Administrator and run the following command:
    Remove-Item -Path HKLM:\Software\Microsoft\SystemCertificates\SMS\Certificates\* -Force
  5. Remove the Inventory Action ID 1 in WMI. You can run the following command:
    wmic /namespace:\root\ccm\invagt path inventoryActionStatus where InventoryActionID=”{00000000-0000-0000-0000-000000000001}” DELETE /NOINTERACTIVE
  6. Once the above steps have been completed, shutdown the master template, capture a snapshot, and provision the VDI systems. At this point, each VDI system will generate a unique ConfigMgr GUID and will function as expected.

For step number 5, this can be achieved by using the wbemtest tool with the following steps:

  • Launch wbemtest as Administrator
  • Click Connect
  • Change the Namespace field as root\ccm\invagt, and click Connect
  • Click on Enum Classes
  • Select Recursive and click Ok
  • Scroll down and locate InventoryActionStatus, and double click
  • Click on the Instances button
  • Select the Inventory GUID and click Delete
