Since you stored the roles of the users in the database, you have to check to the database.
So try to include this method in the global.asax

protected void Application_AuthenticateRequest(object sender, EventArgs args)
    {
        if (Context.User != null)
        {
            IEnumerable<role> roles = new UsersService.UsersClient().GetUserRoles(
                                                    Context.User.Identity.Name);


            string[] rolesArray = new string[roles.Count()];
            for (int i = 0; i < roles.Count(); i++)
            {
                rolesArray[i] = roles.ElementAt(i).RoleName;
            }

            GenericPrincipal gp = new GenericPrincipal(Context.User.Identity, rolesArray);
            Context.User = gp;
        }
    }
</role>

Then you could use this on top of the actionResult methods in the controllers.

[Authorize(Roles = "Administrator")]

Hope this helps.
