  Fix description: This patch is adding a code to check if the value
  of config parameter nsslapd-allowed-to-delete-attrs includes any
  invalid attributes or not.  If it does, the server ignores the
  invalid ones, and the following search returns only the valid
  attributes.  Also, it is logged in the error log:
    nsslapd-allowed-to-delete-attrs: Unknown attribute bogus will be
    ignored
