The cluster is configured to use an authentication service to control which users are authorized to access the cluster.
If the password for the user name has recently been changed on the authentication service, you might be required to force the cluster to refresh its authentication cache. You can force the refresh using the cluster console View Cluster Properties, Remote Authentication panel or by submitting the Command-Line Interface command chauthservice -refresh.
Ensure that the user name and password that you use is correct.
If the password for the user name has recently been changed on the authentication service, force the cluster to refresh its authentication cache.
If the user name that you are using also has a password configured on the cluster, ensure that the password that is configured on the cluster is identical to the password that is configured for that user name on the authentication service.
Resubmit the task.
