You have a self signed certificate,

Correct.

so you don't need to verify your certificate.
When you activate the tls on ldap, you only need this two lines, and you don't
need the line with certificate verification*olcTLSCACertificateFile : *

Wrong.

Procedure:

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.

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

RTFM.

    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
