Title:
  Need support for OpenDirectory in LDAP driver

Status in OpenStack Identity (keystone):
  Fix Released

Bug description:
  It is necessary to support Apple OpenDirectory as the backend for
  Keystone Identity.

  OpenDirectory uses a concept of POSIX groups, when the entities of
  users in the groups are represented as UIDs, not full DNs:

  dn: cn=group1, cn=groups,dc=domain,dc=com
  ....
  memberUid: user1
  memberUid: user2
  ....

  while in the driver of LDAP it is hardcoded that the entities could be
  only full DNs, like:

  dn: cn=group1, cn=groups,dc=domain,dc=com
  ....
  memberUid: uid=user1,cn=users,dc=domain,dc=com
  memberUid: uid=user2,cn=users,dc=domain,dc=com

  Because of this reason it is impossible to use groups in Keystone and
  we cannot assign the roles to the Keystone groups - Keystone doesn't
  recognize any user to be a part of any group. When it checks the
  roles, it searches for the direct user's assignments, and then for any
  groups which the user can be a member of. So by default the search
  returns nothing.

  We have to have an additional parameter in the config where we specify
  the type of the entity in the groups - whether is it currently a dn or
  an id.
