  PROBLEM DESCRIPTION:
  IBM MQ version 8 includes functionality for reaching LDAP
  servers.  To perform this activity MQ's library amqzfud is
  statically linked with the LDAP client library from the IBM
  Security Directory Server product.
  
  During analysis at IBM this issue was believed to be caused
  within the libibmldapstatic library.  The suggestion was
  considered that this was a known issue fixed in IBM Security
  Directory Server APAR IO23916
  http://www.ibm.com/support/docview.wss?uid=swg1IO23916
  IO23916: IDS client applications core in ldap_search or
  ldap_msgfree
  
  However, the problem could not be recreated with or without the
  fix for this issue, and so it was determined that this APAR
  should be closed as unreproducible in the reported release.
