Do you have connection/access logs on the LDAP server to verify whether a
connection is even being established? Also, are you able to try running
those same ldapsearch queries with the IP address(es) rather than DNS names
for your server? The =E2=80=9Ccan=E2=80=99t contact=E2=80=9D initially seem=
s more like potentially
DNS resolution or firewall/connectivity than something LDAP related like
failure to bind successfully=E2=80=A6


Thanks,
