  *                      intermittent LDAP connectivity errors   *

  ****************************************************************
  During a search where paging is required to get all the search
  results from the LDAP server, duplicate users can occur if
  there are intermittent errors contacting the LDAP server.
  For example, if page 2 of search results is requested and a
  ServiceUnavailableException occurs andthe request is
  tried again and successfully connects to the LDAP, page 1 is
  re-requested and appended to the results that already contain
  page 1.
  In cases where there are recurring connectivity issues, the
  duplicates could cause a MaxResultsExceededException that
  would normally not be encountered leading to a search returned
  with no results.
  

Problem conclusion

• The connectivity failure path was modified to not return
  duplicates.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.14 and 9.0.0.9.  Please refer to the Recommended
