I think that could be managed with ldap_perror() to deal with the
connection if the server is down.
If i don't put the perror line in, than there is an exception procuded by
the ldap library.
The same error occurs when you use proftp-ldap and enter the wrong
search-base.

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.
