I'm posting all the information together in this e-mail, hope you can
help me out, I'm quite desperate at this point.
Following your advise I tried to set TLS in my server and client.
I generated the certificates for both client and server (self signed) and
sent the cacert file from the server to the clients.
I started the server like this:
/usr/local/libexec/slapd -u ldap -h ldaps://curri0.imppc.local:636 -f
/usr/local/openldap-2.4.25/etc/openldap/slapd.conf -d 1
( I installed a newer version of openldap in my server as the RH6 uses an
old one, I compiled it with tls and openssl)
From the client I do :
ldapsearch -x -ZZ -d1 -h curri0.imppc.local:636
