Hello MQ Security Users,
After installing security updates on the domain controllers to which the IBM MQ server connects, an error of the following type began to occur:
"
Host(I0MQ01) Installation(Installation1)
VRMF(9.1.1.0) QMgr(QM.INF.EXT)
Time(2021-04-22T09:07:41.773Z)
CommentInsert1(mqmtest@extern)
CommentInsert2(mqmtest@extern)
AMQ8079W: Access was denied when attempting to retrieve group membership
information for user 'mqmsrv@extern'.
EXPLANATION:
IBM MQ, running with the authority of user 'mqmtest@extern', was unable to
retrieve group membership information for the specified user.
ACTION:
Ensure Active Directory access permissions allow user 'mqmsrv@extern' to read
group memberships for user 'mqmsrv@extern'. To retrieve group membership
information for a domain user, MQ must run with the authority of a domain user
and a domain controller must be available. "
After stopping the queue manager, it does not start and gives the above error. The following errors also occur:
"
Host(I0MQ01) Installation(Installation1)
VRMF(9.1.1.0) QMgr(QM.INF.EXT)
Time(2021-04-22T07:07:33.301Z)
CommentInsert1(AMQ9999, AMQ9209, AMQ9208, AMQ9002, AMQ9545, AMQ9001)
CommentInsert2(QMErrorLog)
CommentInsert3(E:\MQ\Qmgrs\QM!INF!EXT\qm.ini)
AMQ6258I: Message exclusion enabled for message numbers (AMQ9999, AMQ9209,
AMQ9208, AMQ9002, AMQ9545, AMQ9001).
EXPLANATION:
The message contains a list of message numbers which have been excluded by
service QMErrorLog from the configuration file 'E:\MQ\Qmgrs\QM!INF!EXT\qm.ini'.
Requests to write these messages to the error log will be discarded.
ACTION:
If you wish to see instances of these messages you should alter the definition
of the ExcludeMessage attribute in the queue manager configuration.
"
Help is needed, where to find the source of the problem.

Contact your AD administration / support team to investigate and resolve ?

Hello gbaddeley.
We've contacted our AD administrators for possible causes of the problem and the need for tracing. In response, we received that there are no problems on the AD side. Authorization and connection requests work fine.
What kind of tracing at the operating system level should be included in order to view the traffic to the AD servers to analyze the situation? |

You do not state whether the installation is running under a domain user or 'local' user.
If the former (domain), request your domain admins check all the settings for the account as per IBM Documentation.
If the latter (local), check that the 'Prepare IBM MQ Wizard' has not been run, and for the question 'Are any of the domain controllers in your network running Windows 2000 or later?' ensure the 'Yes' radio button has not been selected.

The IBM MQ server is running as a domain user. We have checked all the necessary settings on the domain controller. We have a domain controller under the control of the Windows 2012 operating system.
The problems began a month ago when a security update was installed on the controller. The version of IBM MQ we have is 9.1.1.
At the same time, there were problems with different queue managers within the same server. At the same time, it was impossible to get information about different users who log in to this domain. The system has been running this domain controller for 5 years. Before that, there were no problems with reading their authorization rights.

I've experienced the same with IBM MQ 9.3 on Windows 11,
I got it fixed on my environment by adding the MQ user to the Network Configuration Operators group, Currently it's working fine with me. |
