I simulated this by using a firewall rule dropping IP packets.

Use something like this for setting the network timeout before the simple bind:

     l = LDAPObject(ldap_url.initializeUrl())
     l.protocol_version = 3
     l.network_timeout = 2.5 # connect timeout 2500 msec

Note that the l.simple_bind_s() raises the LDAPError exception 
ldap.SERVER_DOWN, not ldap_url.initializeUrl().

The behaviour might only work with recent python-ldap (2.0.0pre14+ according 
to CHANGES) and OpenLDAP libs (tested on my system with python-ldap 2.0.2 
and OpenLDAP 2.2.17 libs).

Ciao, Michael.
