Title:
  LDAP non-URL safe characters cause auth failure

Status in OpenStack Identity (Keystone):
  Fix Released
Status in Keystone havana series:
  In Progress

Bug description:
  An Openstack user attempting to integrate Keystone with AD has
  reported that when his user contains a comma (full name CN='Doe,
  John'), a 'Bad search filter' error is thrown. If the full name CN is
  instead 'John Doe', authorization succeeds.

  dpkg -l |grep keystone
