AD Integration broken after KB5008102

Hello

 

After the installation the security patch KB5008102 on our Domain Controllers, the AD integration is broken:

 

The security account manager blocked a non-administrator from creating or renaming a computer account using an invalid sAMAccountName. sAMAccountName on computer accounts must end with a single trailing $ sign.

Attempted sAMAccountName: xxxxxxxxx$iME
Recommended sAMAccountName: xxxxxxxxx$iME$

 

Link to the Microsoft KB: https://support.microsoft.com/en-gb/topic/kb5008102-active-directory-security-accounts-manager-harde...

 

Unfortunately, uninstalling the security patch is not an option.

Hello SysArch,


Thank you for posting on the Intel® communities.


To continue with your request for assistance can you please provide the following:


1-Do you have a current deployment with Intel® Active Management Technology (Intel® AMT)?


2-If you do have a deployment can you please let us know how many systems did you deployed and what version of Intel® AMT is being used?


3-Can you please let us know how many systems do you have affected by this issue and what type of systems are we talking about? Please provide as many details as possible.


Regards,

Hello Victor

 

1: We do have a current deployment with Intel AMT

 

2: 14'524 Systems with Intel AMT version 11.8.77

 

3: At the moment every new and every reconfiguring system is affected by this (over time this should be every system) as our Active Directory is not allowing modifying or creation of computer objects without a trailing '$' . These systems are in a production environment and are getting periodicaly new staged.  As i understood the issue we are having, this should not only be a problem of our environment? Is there any way to change the naming in the AD-Integration to something with a trailing '$'?

Hi @MichaelA_Intel 

 

I can confirm that we are having the same issue at our end.
Affecting 2500 devices.

We have also opened an support case with Microsoft Premier Support regarding this security update KB5008102 for November 2021.
We are seeing the same error messages in the event logs of Active Directory Domain Controllers.

Best Regards

Hi @MichaelA_Intel  and @SysArch 

I have found an workaround to this problem.

According to KB5008102; this protection and validation check is forced on users who do not have administrator rights for machine accounts that is trying to create or modify sAMAccountName computer accounts ending with with $iME.

The Intel SCS or Intel EMA server machine account is not an administrator account, hence that is why Active Directory refuses these machines accounts to create computer accounts ending with $iME

Ref:
https://support.microsoft.com/en-gb/topic/kb5008102-active-directory-security-accounts-manager-harde...

To workaround this, until proper fix exist, do this:

1. Add the AD machine account of "Intel SCS" or "Intel EMA" server as member of the "Administrators" group in Active Directory.

2. Reboot the "Intel SCS" or "Intel EMA" server


This allows you to provisioning the Intel AMT devices again with the ComputerName$iME.

This is of course an ugly workaround and nothing you want to run for an very long time in your environment, but it is the lesser of two evils right now!

This allows you to both run the current security updates for November 2021 while this problem is sorted out with permanent fix and at the same time allows you to continue to provisioning Intel AMT devices.

Above workaround works perfect for us.

Use it for what it's worth!

Best Regards
Horgster

Thank you for sharing this workaround. Unfortunately, getting my SCS service account approved as a domain admin is about as likely as security approving a removal of the cumulative security patch. But others might have more luck with that.

@JRüeg 

That is fully understandable.

But please be aware that I did write "Administrators group", not "Domain Admins group".
Right now, this is the less of two evils until permanent fix exist or better workaround exists.

We did open a Microsoft case and after some back and forth adding the user to the administrators group in the domain is the only available workaround. There is no other way to delegate the needed permissions and there is no other workaround planned. The solution according to Microsoft is for Inel to update their product.

The answer also containes information that "there are plans to apply the same enforcements" for users in the administrators group as well. So this workaround will not be a permanent solution even if it is not a security concern in your company.
