Title:
  Group lookup by name in LDAP via v3 fails

Status in Keystone:
  Fix Released
Status in Keystone kilo series:
  In Progress

Bug description:
  This bug is similar to
  https://bugs.launchpad.net/keystone/+bug/1454309 but relates to
  groups. When issuing an "openstack group show <group_name>" command on
  a domain associated with LDAP, invalid LDAP query is composed and
  Keystone returns ISE 500:

  $ openstack --os-token ADMIN --os-url http://localhost:35357/v3 --os-identity-api-version 3 group show --domain ad 'Domain Admins'
  ERROR: openstack An unexpected error prevented the server from fulfilling your request: {'desc': 'Bad search filter'} (Disable debug mode to suppress these details.) (HTTP 500) (Request-ID: req-06fd5907-6ade-4872-95ab-e66f0809986a)

  Here's the log:
