# Username

The name of the user running the action. IDOL Category Component checks if this user belongs to a role that has appropriate cluster access permissions to run the action.

If users attempt to run a cluster action that they do not have permission for, IDOL Category Component returns an authentication error.

When the list of roles is empty (that is, when you have not set access permissions for any roles), all users can perform the action. If you have set access permissions for at least one role for the job name and output type, but do not provide the `Username` parameter, IDOL Category Component returns an authentication error.
