                             String role)
```
    Return true if current user is in the specified role. Only providers that support role based access should implement this method. For others it checks the subject for the presence of Role grant of the specified name. This method is defined to conform with one of the most commonly spread authorization concept, as it is required for frameworks such as Servlet and JAX-RS.
    
    Parameters:
    
    subject - current subject
    
    role - role name
    
    Returns:
