问题
I am "very" new to IBM Websphere Mq, I'll try to give as much details as possible.
I've got Websphere MQ 7.1 installed on Windows server 2003 running on Vmware Workstation. The Host is running Windows 7 with Websphere MQ Client and my ASP.NET application. (My application is supposed to connect to Windows server 2003 Websphere's Queue manager via SVRCONN channel, the Websphere client installed on the host is used just for testing purpose, connecting WMQ Client to WMQ Server results in an AMQ4036 access not authorized error, which leads to conclusion server configuration needed!)
Both System can ping each other and are on the same local network. (did I also mentioned that port 1415 is opened and TCP listener is running on the server virtual machine?)
ASP.NET code segment :
queueManager = new MQQueueManager(queueManagerName, queueProperties);
with queueManagerName matching the server's queue manager and queueProperties as following:
queueProperties[MQC.HOST_NAME_PROPERTY] = "192.168.203.128";
queueProperties[MQC.PORT_PROPERTY] = 1415;
queueProperties[MQC.CHANNEL_PROPERTY] = "QM_TEST.SVRCONN";
queueProperties[MQC.USER_ID_PROPERTY] = "";
queueProperties[MQC.PASSWORD_PROPERTY] = "";
when compiling I get the MQRC_NOT_AUTHORIZED exception and this following logs in AMQERR01.log on server side (NOTE: The IBM WMQ is installed in french language, the logs are generated in french, but I think you'll manage to understand the error.)

(note that i have added couple rules, and USERID Hatrix does not exist, i have included it in a SET CHLAUTH command for testing purpose)
I thought it has to do with MCAuser so I gave it a try with the MCAuser set to "Administrateur" (which is the admin's name on WMQ) and connecting with:
queueProperties[MQC.USER_ID_PROPERTY] = "Administrateur";
Still gives me the same error but with different server side log output:

What I couldn't understand is, what's the use of USERID and PASSWORD in the queuemanager properties in ASP.NET where the USERID identified in WMQ is "Hatrix" (which is the windows 7 account's name).
Do I have to create a new USERID "Hatrix" in WMQ in order to make my code works? (i couldn't figured out how )
Thanks in advance,
MqDebug.
回答1:
First issue is that the QMgr must be able to resolve the ID passed to it. That means the ID either is defined locally or in a domain to which the QMgr has access. Normally, permissions are granted on the group and if so then it too must be resolved by the receiving QMgr.
Now comes the question of what, exactly, does the QMgr resolve? When you have a connection from a Windows machine to a QMgr on a Windows machine then the ID that is passed by the channel is the Windows SID which is a Universally Unique Identifier (UUID)and not the text string. Similarly, the group resolves to a Windows SID.
So, for example, you may have an ID called ADMINISTRATEUR defined locally on two Windows boxes and it still fails. The errors will say that the ID presented was ADMINISTRATEUR and that the ID is not authorized and you can clearly see in the dspmqaut commands that ADMINISTRATEUR is authorized. Except what is happening is that ADMINISTRATEUR on one host has its unique UUID and the account of the same name on the other host has a different UUID and Windows is looking at the UUID and not the text string.
When you have the same ID defined in multiple places, the QMgr must be able to differentiate between them. When it cannot, strange and unusual things occur.
For example, let's say you define a channel with MCAUSER('hatrix') and then run setmqaut -p hatrix. Let's further stipulate that the hatrix ID is not defined locally but rather is defined in both DOMAINA and DOMAINB and that when the command is run, the DOMAINA domain server is first in the search path.
The setmqaut command resolves the name hatrix to a UUID defined in DOMAINA.
Later due to normal activity in the network, DOMAINB rises to the first spot in the domain search path. Now when the MCAUSER('hatrix') attempts to connect, the string hatrix resolves in DOMAINB which is a different UUID than the one the setmqaut command resolved. The channel which was connecting normally suddenly throws a 2035 error.
The answer to this problem is to qualify both the setmqaut command and the MCAUSER value with the desired domain. For example, setmqaut -p hatrix@DOMAINA and then MCAUSER('hatrix@DOMAINA') will work regardless of whether DOMAINA or DOMAINB are first in the search path, or even if hatrix is defined locally on the WMQ host server. (Assuming that hatrix is indeed defined in DOMAINA of course.
As a rule, you generally do not want to use the -p option on setmqaut commands. The only exception is Windows hosts, and then only when the ID is qualified with a domain or server name as shown above.
Finally, leaving the channel's MCAUSER blank is what allows your Windows ID to flow to the MCA and be used for authorization checks. What you need to realize is that there is no authentication going on. Yes, it's true that the Windows client will send its Windows SID. However if you run a Linux VM on your Windows box and connect with that, there is no SID to pass and so the Windows QMgr falls back to resolving the string value of the ID. That means anyone can connect to that channel as any ID just by asserting the desired ID from a non-Windows client.
So, strongly authenticate administrative connections with certificates. For low-privileged connections, use CHLAUTH rules or an exit to set the MCAUSER rather than letting it flow through, and then use setmqaut to make sure that MCAUSER is not administrative. That means never grant +set on the QMgr and +crt on queues to non-admins and avoid +setid, +setall wherever possible.

回答2:
Use setmqaut to assign permission to "Hatrix" UserID but it is better to do it against a group rather than a UserID.
回答3:
fixing...the command is
setmquat -m qmgrname -t qmgr -p username +allqmi
whrere: qmgrname is the name of qmgr username is the account name under eclipse is running and that account is not in ban list.
