  3. The view <code class="literal">enabled_roles</code> identifies the currently
  4. <span class="quote">“<span class="quote">enabled roles</span>”</span>. The enabled roles are recursively
  5. defined as the current user together with all roles that have been
  6. granted to the enabled roles with automatic inheritance. In other
  7. words, these are all roles that the current user has direct or
  8. indirect, automatically inheriting membership in.

  12. For permission checking, the set of <span class="quote">“<span class="quote">applicable roles</span>”</span>
  13. is applied, which can be broader than the set of enabled roles. So
  14. generally, it is better to use the view
  15. <code class="literal">applicable_roles</code> instead of this one; See
