LDAP_X_OPT_CONNECT_TIMEOUT is applicable only when a new connection
being established. in your case that happens when you execute bind
operation. now i dunno why your LDAP server is changing its IP addr
dynamically and how it does the cleanup but normally you should get
LDAP_SERVER_DOWN from ldap_search_s() if that happens clean. there
were several fixes made to "connection down" handling in libldap
since 5.08 version so you might wanna upgrade to the latest version
and see if LDAP_SERVER_DOWN gets returned straight away or not.
