Adding Cluster Administrators and Users

Updated: June 6, 2006

Applies To: Windows Compute Cluster Server 2003

Before a cluster can be administered or used, you must add domain users or groups to the Users and Administrators security groups on the head node.

When you add new users and administrators to the cluster using the Manage Users Wizard, the changes in membership are propagated to all compute nodes that have been approved for inclusion to the cluster. Nodes with Pending Approval status do not receive the updated administrator and user group Information until approved.

The following table defines the roles of cluster administrator and user:

Cluster Administrator
Cluster administrators have full access to all nodes on the cluster and automatically become members of the local Administrators group on each node in the cluster. Cluster administrators can use the Compute Cluster Administrator to add and remove compute nodes and add or remove cluster users. Administrators can use the Compute Cluster Job Manager or issue commands from the command-line interface (CLI) to submit jobs and manage the job queue.

Cluster User
Cluster users can submit jobs by using the Compute Cluster Job Manager or the CLI. Users will be able to see the entire job queue and can only modify their own jobs. Jobs will run using the user credentials of the person who submitted the job; as a result, the job can only access resources and services during job execution under the rights of that user.

To add or remove cluster administrators and users

  1. From the To Do List in the Compute Cluster Administrator, on the Cluster Security tile, click Manage Cluster Users and Administrators.

  2. On the Before You Begin page, note the information displayed and click Next.

  3. On the Cluster Users page:

    1. If you want to add one or more users, enter a user in the format domain\user and click Add. Repeat for every user you want to add. You can also add a domain user group to the list of cluster users. Click Next when finished.

    2. If you want to remove one or more users from the list of cluster users, click each user in the large text box, then click Remove. When finished, click Next.

  4. On the Cluster Administrators page:

    1. If you want to add one or more users as cluster administrators, enter a user name using a domain\username format, then click Add. You can also add a domain user group to the list of cluster administrators. When you are finished adding users and groups as cluster administrators, click Next.

    2. If you want to remove one or more users form the list of cluster administrators, click each user in the large text box, then click Remove. When finished, click Next.

  5. On the View Summary page, review the changes you have intend to make to the cluster users and administrator groups. If you are not satisfied with the changes being made, click Cancel and start over. If you are satisfied with the changes you are about to make, click Next.

  6. A Progress page is displayed, often briefly. After your changes have been committed to the cluster administrators and users groups, the Result page is displayed and describes what was done. Click Finish to close the wizard.
