When I try to access IBM MQ remotely, I get the errors below in my log file. Could someone give me some tip about what could I do to solve this?
AMQ5534E: the authentication user id usermq failed.
AMQ5542I: The authentication verification with fail was caused by configuration CONNAUTH CHCKCLNT (RECDADMIN) of queue manager.
I asked my network administrator to create another user for me to make the access, but didn't solve.

We have application which was using by Customer and customer like to update authentication from our application to AD from NTLM to Kerberos. Based on this article, it may have to be done by early 2022.
https://support.microsoft.com/en-us/topic/kb5004442-manage-changes-for-windows-dcom-server-security-feature-bypass-cve-2021-26414-f1400b52-c141-43d2-941e-37ed901c769c
In the document below, it is listing the different levels that are required, and Microsoft is stating that RPC_C_AUTHN_LEVEL_PKT_INTEGRITY or higher is required shortly. Right now the error we are having on their DC's from Our application authentications is that the user in our AD scope under passive ID for monitoring is attempting to connect to our domain at too low of a security level.
https://docs.microsoft.com/en-us/windows/win32/rpc/authentication-level-constants
In our application Admin Web UI we are geeing the issue:
The connection was tested on '' PassiveID active node.
Connection to 'ws2022-a.lab2022.local' failed.
Access is denied. Please check credentials, permissions and configure the Windows machine for WMI access.
In AD event viewer > Administrative Events: 10036 Errors. which says that
"The server-side authentication level policy does not allow the user LAB2022\dev-admin SID (S-1-5-21-4164125427-177154609-51000486-1108) from address to activate DCOM server. Please raise the activation authentication level at least to RPC_C_AUTHN_LEVEL_PKT_INTEGRITY in client application".
Can anyone help me how we can fix the issue from application side since MS workaround was not working(disabling the registry key in DC)?
we found some possible solution from sourceforge forum site discussion (https://sourceforge.net/p/j-interop/discussion/600729/thread/731d99133f/) that need to fix the issue in third party library j-interop-ng and tried the solution to set the sign and seal flags in JIComserver.java before init() block but not worked as expected.
We are using j-interop-ng-3.0.jar in our application and need some quick solution to fix the issue further to work the WMI provider.
I'm trying to setup a Client connection to IBM MQ and test this using the samples application wmqjava.
I am able to connect in binding mode but I'm getting a 2035 unauthorised error when using client mode.
The steps I've taken to set this up are:
Create / run a queue manager
Create a listener
Create a SVRConn channel (multiple attempts)
I think I'm missing something with authorisation?
DEF CHL('TEST2.CHANNEL') CHLTYPE(SVRCONN) TRPTYPE(TCP) MCAUSER(' ')
I'm trying to connect to this on the same machine that the MQ server is running on.
Depending on the version of IBM MQ you are using, you could be being blocked by the default CHLAUTH rule which bans client connections which assert privileged user ids, or the default CONNAUTH rule which demands a password is provided for such a client connection.
Read Getting going without turning off MQ Security for instructions on how to turn both off, or use both correctly.
FYI: Your queue manager error log will tell you the reason you were blocked from accessing it.
You can put the user "mqm" in MCAUSER Field to bypass all the authorisation.
DEF CHL('TEST2.CHANNEL') CHLTYPE(SVRCONN) TRPTYPE(TCP) MCAUSER('mqm')
This will use all the authorities of mqm user (Default MQ admin user) to connect to Queue Manager.
Alternatively you can authorize the user to allow to connect, put, get messages.
setmqauth or getmqauth commands can help you.
Ok, I am completely stumped here. I am running the Jenkins application (v1.635) for Mac OSX. I am trying to connect to Active Directory through the LDAP Security Realm. No matter what I try (and I have tried a good 30+ variants), the login fails and nothing gets written to the jenkins.log file.
I have ApacheDirectoryStudio installed and it connects flawlessly, so I know it is a Jenkins issue (and not a network or ACL issue).
The LDAP server is using a self-signed SSL certificate, which I installed into the relevant cacerts file.
Here's my LDAP configuration (minus the sensitive corporate stuff)
Server: ldaps://subdomain.domain.com:636
root DN: DC=domain,DC=com
User search base: OU=Users and Computers
User search filter: sAMAccountName={0}
Group search base: OU=Jenkins Groups,OU=Groups
Group search filter: (&(objectclass=group)(cn={0}))
Group membership: Parse user attribute for list of groups
Group membership attribute: memberOf
Manager DN: CN=jenkins,OU=Users and Computers,DC=domain,DC=com
Manager Password: password
Display Name LDAP attribute: displayname
Email Address LDAP attribute: mail
Disable Ldap Email Resolver: unchecked
Any help is greatly appreciated. Even getting the log file to spit out some info would be great.
Thanks!
Edit #1: Sometimes an exception does show up in the log file. Hopefully this helps.

Edit #2: I have to go to an 1 1/2 hour meeting, so my responses will be delayed. Sorry.
So it's not ideal, but I was able to get the connection to work with the plain ldap connection (not ldaps). All I can figure is that Apache Directory Studio is smarter than Jenkins when it comes to establishing the connection. I suspect there may be an issue with the self-signed SSL certificate chain that Jenkins can't quite figure out. I really wish there was more verbosity to the logs in this matter. But for now, I have it working and since it is behind the corporate firewalls, the non-secure connection is less of a risk. I still intend to figure out the root cause, but for now, this will have to do. Thanks for your suggestions.
I installed LDAP server on my virtual machine(centOS) running on windows, now I want to access it from windows
So how do I enable remote access to LDAP server.
I tried installing 389 Directory Server (which is actually meant for fedora), on some forum I heard its a easy GUI to do the command line jobs easily, but I did not find the option to enable the remote login or any ip filters.
Note:
I am trying to use Java to login the LDAP server for authentication and authorization, for that I am using unboundid api
You can suggest which api should I use, I am just a beginner.
Update:
my java code
LDAPConnection ldap = new LDAPConnection("http://xxx.xx.xx.xxx", 9830);
error
an error occurred while attempting to connect to server http://xxx.xx.xx.xxx:9830: java.io.IOException: An error occurred while attempting to establish a connection to server http://xxx.xx.xx.xxx:9830: java.net.UnknownHostException: http://xxx.xx.xx.xxx')
I also tried ldap://xxx.xx.xx.xxx instead of http://xxx.xx.xx.xxx
Don't specify the server address as a URL. Just specify the address as either an IP address or resolvable name. So instead of "http://xxx.xx.xx.xxx" just use "xxx.xx.xx.xxx".
I am using MQexplorer to handle queue manager, and when I connect to MQ using JMS with JNDI lookup, using qcf.createQueueConnection(); I am getting JMSWMQ2013: The security authentication was not valid that was supplied for QueueManager error. All posts/blogs mention about this error, but they say to remove CHAUTH for queuemanager and so on... How do I work this out using MQExplorer? Please help me on this!
I am using MQ client(with JNDI on LDAP) connection which can connect remote machine(not bindings).
Actually disabling CHLAUTH is NOT advised as doing so opens up your queue manager to the world. It's OK if this is a test queue manager. Using runmqsc you can disable channel authentication. In runmqsc issue "ALTER QMGR CHLAUTH(DISABLED)" command to disable channel authentication.
Please read WMQ InfoCenter or Chapter 20 of this redbook or just search for T.Rob's posts in this forum on CHLAUTH. Few links here, this one
