Users must have a role assigned on the cluster before they can perform any management tasks.
The available roles for a cluster user are Cluster Administrator, Cluster Operator, Group Administrator, or Group Operator. You can select more than one, but be aware that some option combinations are redundant.
To begin this procedure, you selected a single cluster from a Clusters Listing table. If you select a role of Cluster Administrator or Cluster Operator, you have already specified the object to which the user's role applies. You are not required to specify anything more, so the service group selection boxes are unavailable.
If you select Group Administrator or Group Operator, you must select at least one service group. To select a service group, click a service group name under Available Groups and then click the right-arrow button. To reject a service group, click a name under Selected Groups and then click the left-arrow button to return it to Available Groups.
Note This procedure does not validate the user account. For a cluster that is configured in secure mode, the account is assumed to exist on the domain. For a cluster that is not configured in secure mode, the account is assumed to exist on the cluster.
Note You cannot delete the user account that is currently logged in.
