  500 error

Status in OpenStack Identity (keystone):
  Fix Released
Status in OpenStack Identity (keystone) icehouse series:

Bug description:
  Keystone raises a 500 error when trying to use paging on an LDAP
  server that doesn't support it (by setting [ldap] page_size to a non-
  zero integer)

  # keystone user-list
  An unexpected error prevented the server from fulfilling your request. {'desc': 'Critical extension is unavailable'} (HTTP 500)

  And this is the keystone.log traceback:

  IMHO, there should be a better error message and no 500 error should be raised.
