It true and false, with debian and openLdap compiled with GnuTLS (my case), i
read this documentation :
http://wiki.debian.org/LDAP/OpenLDAPSetup and they said :

Pure garbage.


You're going to need the gnutls certificate generator: certtool

Run these two commands to generate a new self-signed key (into the current
working directory):

certtool --generate-privkey --outfile ca-key.pem
certtool --generate-self-signed --load-privkey ca-key.pem --outfile ca-cert.pem

Then, update your certificate locations in /etc/ldap/slapd.conf
(TLSCertificateFile points to ca-cert.pem and TLSCertificateKeyFile points to
ca-key.pem), *comment out TLSCACertificateFile*, and change *TLSVerifyClient
to never.*

In /etc/ldap/ldap.conf, comment out TLS_CACERT and change TLS_REQCERT to never.

This is utterly bogus. Turning off these checks disables any spoofing detection; you might as well run without TLS at all.

Since the certificate is self-signed, we can't have gnutls trying to verify it
(hence the never), otherwise it will never run.

And RTFM is a little violent, i try to help with my little experience, i'm not
an expert for sure.

RTFM is exactly the correct response.

Yeah, It shows output containing ber_dump, ldap_write,ldap_read,
tls_write, tls_read etc. But at the end is shows the following:

TLS certificate verification: Error, self signed certificate
TLS: can't connect: error:14090086:SSL routines:SSL3_GET_SERVER_
CERTIFICATE:certificate verify failed (self signed certificate).
ldap_start_tls: Connect error (-11)
additional info: error:14090086:SSL
routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed (self
signed certificate)

Why it shows an error ? and how to resolve this?

and when I do ldapsearch with -ZZ option it gives error

$ldapsearch -x -v -D "cn=root,dc=abc,dc=com" -w cluster -b
"ou=People,dc=abc,dc=com" "uid=ldap_6" -h n0 -ZZ
ldap_initialize( ldap://n0 )
ldap_start_tls: Connect error (-11)
additional info: error:14090086:SSL
routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
