Using Windows NT Domain Authentication  
 
 

Before you can enable NT domain authentication on any specific cluster, you must create an NT user group with a name in the form: "BT_clustername" within the domain you want to secure.

You or the domain administrator can do this through the standard Windows NT User Manager for Domains utility. Once you create a "BT_clustername" group, any of the users you add to that group are authenticated to view the cluster. All members of the cluster must be from the same Windows NT domain unless a trusted relationship has been set up between two or more domains by the system administrator.

A "BT_clustername" global group must exist in the domain from which the ClusterCATS Explorer is executed. Cluster members in other domains need only the trust relationship. ClusterCATS Explorer determines what servers exist in which NT domain by communicating with any Windows NT domain controller for the domain. The list of servers that exist in the Windows NT domain can be viewed by looking at the Network Neighborhood Windows NT utility. If no trust relationship exists, then cluster members must be from the same Windows NT domain.

 
 
  To set up Windows NT domain authentication:  
 
  1. You or someone with administrator privileges in the NT domain where all of the servers reside must create a new security group. The group name has to take the form: "BT_clustername." You'll need to go up the domain hierarchy until you reach a common level for all servers in the cluster.
  2. Log into the domain as administrator, Start Programs > Administrative Tools > User Manager for Domains.
  3. Select User>New Global Group. Add the group name and then add yourself as a member of the group. You can now administer that cluster. To add other administrators, simply add them to the same BT_clustername group. Ensure that this process is completed before you complete the next step.
  4. In the ClusterCATS Explorer window, right click the icon of the cluster where you want to configure authentication and select Properties from the popup menu.
  5. Click the Administration tab on the cluster properties dialog.
  6. In the Authentication field, NT domain, click OK. Authentication for the selected cluster is enabled. Only authorized administrators (people who are part of the BT_* group created in the Step 1) can add that cluster to their view.
