I've followed the instructions in the FAQ. The issue has been assigned #4389.
A document which I also found useful in obtaining the necesasry
information is http://www.linuxfocus.org/English/July2004/article343.shtml.
You might want to link to that from
http://www.openldap.org/faq/data/cache/59.html.
Not having done anything in C(++) for years and not having done
anything serious in these languages ever, learning how to perform some
of the most basic debugging tasks was long overdue. Hopefully, in the
future my issue submissions will become more accurate.
Please let me know if you need any more information, or if you just
want to blow some steam about the nth clueless issue submission by nth
clueless user ;-)
Thanks for your time and your patience so far,
