> # As Ambari admin, create a user and provide "Cluster User" role. On my cluster the user is named *cluser*
> # Login with the newly created user account
> # Type the URL of some of the pages where "cluster user" is not allowed access like:
>  -- /views/ADMIN_VIEW/2.4.0.0/INSTANCE/#/ 
>  -- /#/main/admin/serviceAccounts
>  -- /#/main/admin/kerberos
> and so on 
> Note - In some cases you may have to load the page twice after typing the URL
> *Result*: The pages are accessible. In one case, it allowed me to rename the cluster from Admin page too. 
> Tried few other operations too with cluster user like create user, change user group, but so far none of them is successful. Even though UI permitted them.
> This presents a security risk as unauthorized users may still have access to undesirable piece of information.
> It would be good to point them to the home page in case they try accessing a page that they are not allowed to
