Lucas goes on to tell us how to re turn on support for repository roles and as he says switch off product support. He goes on to talk about working with roles, creating roles, granting roles, granting roles to other roles and users, reconciling roles, revoking roles, revoking privileges and deleting roles.
This is a very thorough and interesting article and well worth reading. Again it can be found here.
