Thanks for the response.  This program works fine if the ldap server is
available at all times.  Try to put a break right before ldap_search_st()
and stop the ldap server at that point.

I am working on ldap based auth modules for saslauthd/saslv[12] and I am
testing the recovery from ldap server outages.
