Delete role not implemented on assignment LDAP backend

[Marcos Lobo]

Delete role action is not implemented on the assignment LDAP backend in Havana release. Otherwise, other role functions are implemented.

When you try:

curl -X DELETE --insecure -H "X-Auth-Token:the_token" https://localhost:35357/v3/roles/role_id

Keystone raises warning message: "The action you have requested has not been implemented."

The problem is "assignment/ldap" backend is not implementing list_role_assignments function, so python search up in the hierachy and arrives to assignment/core.py list_role_assignments fucntion and raises the NotimplementedException.

Obviously there's already a (near trivial) patch available to resolve this bug, but this comment also applies here, unless someone is invested enough in this deployment pattern to support this approach keystone:

    LDAP Assignment does not support grant v3 API

    The LDAP assignment backend is missing support for several of the v3
    APIs. This patch implements Role Grant CRUD for V3 Assignment API:

    - Role Grant CRUD
      + create_grant
      + get_grant
      + delete_grant
      + update_grant

    - GET /role_assignments
      + list_role_assignments
