Thats strange but if the ssytem person removes domain admin it does not work we again get authorisation errors.

We are still working on it may be we ahve found a temporary solution ,just trying to isolate the issue.

You need a local group, which should contain the domain user, and to set the necessary authorisations for that local group - bread-and-butter (or auths 101 if you prefer) MQ admin.

Surprisingly when the System admin removed Domin admin from the list of previages we again see the authorisation errors 2035.

We still are researching on the issue like need to find permanent solution, logically that does not sound to be permanent solution of adding domain admin.

Anyways i have worked with weblogic JMS and Jboss but truely MQ i am loving it , really good.

Does the domain id have query group membership (delegate) user rights?

Hi Jason,

The group is mqc configured at domain controller and the group is assigned to domain_mqc

For user concerned, this is the configuration at Domain controller.
user mqc_tasco assign it to
Domain admins
Domain mqc
Domain users
mqc

Same user is created at client machine and assigned to mqm group

Than MQ previlages are been assigned to Qmanager ,queue,channels

So you have Domain group mqc, domain user mqc_tasco, who is a member of domain mqc. At the local server, domain group mqc (or the domain id, if you want to do that) is in the local mqm group? All sounds fine so far..

Have they given group mqc Read Group Membership and Read Group MembershipSAM user rights?

http://publib.boulder.ibm.com/infocenter/wmqv7/v7r0/index.jsp?topic=%2Fcom.ibm.mq.amqtac.doc%2Fwq10840_.htm

You do not need domain admin rights for the MQ account.

A local user, i.e. NOT domain? If so, why?

Hi jason ,

I did checked regarding Read Group Membership Read Group MembershipSAM which are allowed.

Logically you are right any mq client should not have domain admin rights.
System admin is taking care of thi issue now.

I did not understood exerk question.

You stated in a previous post:

"...For user concerned, this is the configuration at Domain controller.
user mqc_tasco assign it to
Domain admins
Domain mqc
Domain users
mqc...
"

And in the same post:

"...Same user is created at client machine and assigned to mqm group..."

The above two statements imply that you have:

1. Created a domain user named mqc_tasco, and
2. Created a local user named mqc_tasco on the client computer.

Is that more understandable?

yes you are right..

Your understanding is correct same local user is created at client machine which is at different geographical location.

At client machine
User :mqc_tasco assigned to mqm
Group:mqm

Yes let me explain you this !!!

We ahd tried the same configuration on 2 physical machines connected in LAN without domain controller that time on client machine we created a user and assigne to mqm group.

The same user was created on the machine hosting MQ server assigned to mqm group at that time we did face authorisation error 2035 but after giving previalges at MQ level like Qmanager,queue,channels everything worked.

Now the same environment we created in UAT but this time domain controlelr was there as aprt of project so we went this configuration.

As i am new to MQ and from background of weblogic application server ,if my appoach is wrong to handle the issue , please let us know , your suggestion will really appreciated.

For your UAT set-up, for your client, you need:

1. A domain group, e.g. tasco_clients;
2. A domain user, i.e. mqc_tasco, within the above group;
3. On the WMQ server, create a local group, e.g. tasco_local;
4. Add the domain user, i.e. mqc_tasco, to the above group;
5. Set the relevant authorities on the queue manager for the local group tasco_local.

The above presupposes that you are running the MQSeriesService on the WMQ server under a domain user.

NOTE: the domain group is a useful way of containing any client user IDs, but strictly speaking isn't absolutely necessary.

Hi Exerk,

Wonderfully explained really appreciated.
The tasco_client group on client machine ,whether it has to be under mqm group or not required.

Other than that i got your point regardign running a user under domain previlages.

I will try out few thing by removing everything ,domain admin ,domain user and according to ur design ,it shud work.

You don't want ANYBODY that is not mqadmin in the mqm group anywhere.
Make sure you give connect and inquire to the qmgr object ...
